The gang emerges from the dwarven burial chamber back out into the long hall on the edge of the second floor of the large open room.
Three crumbling bridges span the room from their side to the other and they see what appears to be three foray entrances where they termnate on the other side.
The 80 ft long bridges are supported in the middle by the pillars which rise up from the floor below. The northern most bridge is damaged and partially fallen on the other side of the pillar support. The center bridge is entirly missing a 12 ft portion on their side of the pillar support and the southern most bridge appears to be damamged on the pillar support side nearest them.
Lorath, the lightest member, casts tensers floating disc and both Eblynn and Grim ride on it and tie a rope around his waist as he tries walking across the northern most bridge. As he passes the pillar it collapses under his weight as the disc follows 20 feet behind him. Eblynn and Grim brace themselves as he swings from the rope like a pendulum but is able to catch himself against the pillar and takes no damage. From the center they are able to see a statue of a dwarven smith in the small entry on the far side.
They go back and decide to try the southern most bridge next in the same manner. This time Lorath is able to make it to he other side but where they discover frescoes adorning the walls which they avert their eyes in fear since they were recently entthralled by the other fresco. They also find an ancient anvil covered in cobwebs. Removing them reveals runes which Eblynn recognizes as Dwarven which read “Let the hammer fall and the anvil ring.”
Grim strikes the anvil with one of his tools and it rings but nothing more happens. They Then decide to examine the frescoes and in one of them they discover a dwarvish smith weilding a hammer with runes carved in it which read “Let hearts be lifted and battles won.”
Grim examines it closer and discovers it is not just part of the fresco but an actual hammer which he is able ot remove and use to strike the anvil at which point a loud ring echoes through the chamber. Everyone in the chamber hears it clearly and they all gain 10 temporary hit points.
There is little more in the room so they head back. Lorath nearly loses his footing but it pulled back by Grim and Eblynn reflexively casts feather fall on him.
Once they are back they decide the that Colossus will attempt to make the 12 foot jump with a 100 ft rope tied around his waist and secured at one of the giant stone hammers which server as pillars on the platform they are on.
Colossus takes a running start and feels the bridge give way under his feet but it still able to easily land safely on the other side. He then walked across the rset of the bridge and finds what appears to be a large adminatine door with some runes on it and some old decaying dwarvish armor.
Colossus puls the rope taught and they group then crosses by crawling along under it. Once more of them arrive they help him. The only one to lose their grip is Eblynn who does so right over the gap in the brdige. He free falls for a moment before he is able to cast feather fall on himself and lands safelty on the floor of the room 60 ft below. He makes his way back up the stairs and past the problematic fresco and tries again but this time he ties himself to the rope and makes it without problem.
One the other side Eblynn reads the runes on the door as “A secret never before told will part Dumathoin’s lips.”
Lorath immediately blurts out that he once peed on his cat when he was a child and never told anyone. As he finishes the sentence the floor beneath them gives way and a spiral staircase is reveled. The group heads down.
They emerge some 120 feet below into a large chamber.
Although deep underground, this vault is lit by streams of sunlight that pour down from the ceiling, catching motes of dust in their luminous pools. Ornate columns support a thirty-foot-high vaulted ceiling, which is adorned with carvings of dwarves basking in the presence of their gods. Deep alcoves line the walls and from a large area they catch the glimpse of a mountain of shining gold.
A booming voice says “I wasn’t expecting anyone,” “As you can see, the place is a mess. Perhaps you should come back later, after I’ve tidied up a bit.”
They approach to see a huge adult gold dragon lounging on the hoard of gold and grasping an ornate, two-pronged staff in one claw.
At this point Golorr speaks to Lorath and expresses how pleased he is to finally be in the presence of a worthy intellect. He also notes that the dragon's name is Aurinox and the staff if the fables sragonstaff of Aghairon.
Upon hearing this Lorath probes further and learns that Aghairon of course was a powerful mage intrumental in the foudning of Waterdeep and the staff is a tremendously powerful artifact particularly concerning dragons.
The group treats with Aurinox truthfully and tell them their situation as well as information about the city and the curent open hand and blackstaff. Aurinox for his part expresses that he has been alone a long time with his thoughts and deep down he always knew the gold was ill-gotten and he let his own greed get the best of him. Not for the gold but for the staff of power. It possesses, he says, certain and significant advantages with respect to his kind. Golorr revelas these to Lorath to be advantages on the breath weapons of dragons as well as the ability to command them and even to allow them past the ward the city enjoys which prevents them otherwise.
Aurinox does not doubt their intentions but is prudent and will not allow them to take a single coin until he has been able to negotiate with the open hand herself.
He also says that he will make it a requirement of any deal he reaches with her that they are able to retreive the gold which was promised them.
The group senes he is being truthful and also that he is immensely powerful and that no one will be able to touch the gold without his permission.
They bid him farewell and head back up the spiral stair case to fetch the lord silverhand.
Once they climb down the rope and reach the bottom floor again their eyes again begin to adjust ot the darkenss and they notice an area of seemingly magical darkness across from them. At the same moment some figures emerge.
Zardoz Zord, the captain of the Sea Maiden's faire which they had dined with some nights previous approaches them and speaks.
He greets them warmly and says he is so happy and suprosed to find them there. He is flanked by the three Drow gunslingers they fought in the tower and along the roof tops and alley as well and as three other drow wearing hoods and masks which conceal their faces.
“Zardoz” offers them 5000 gold to turn over the stone to him and leave immediately. When they respond defiantly he says he only seeks to return the money to the people of waterdeep and that neveremeber is the real villain here. He only wants to see neverember and his new government is neverwinter forced out of the Lord's alliance as well as th city of luskan, given membership. Turk takes this opportunity to sneak away and flank the drow along a column to the norht. The party remains defiant and as tensions rise and the drow aproach to forms appear suddenly next to the gang.
The open lord silverhand stands brandishing as sword and the blackstaff safahr stands next to her and leans to the group and says “Leave Jaraxle to us, you handle the other drow”
Silverhand says “Jaraxle of house Baenre, master of the bregan D'earth, pirate warlord of the vile city of sails, Lusken, you are trespassing in this city and meddling in affairs beyond your station. I, the open lord, command you to come with me at once.”
At this the figure known the party as “Zardoz” bows deeply and says “Madame, you wound me. I only...” and before he finishes his sentence he wheels on his heels and twirls a cloak. Those who can see him see a breif moment where his disguise drops revealing a tall elegant drow with sharp features and long white hair. At this Silverhand takes flight and her sword bursts into bright flame. In a scant moment he disappears but the light of the sword revelas a trail of dust is kicked up along the floor of the ancient room. The trails blazes toward the door as the blackstaff disappears in a misty cloud.
As the dusty trail exits the door a large hole appears on the floor suddenly and a fraction of a moment later the blackstaff reappears in a puff of mist teetering on the edge of it but the silverhand is not flying over it and grasps he lifting her off the group and despositing her on the other side.
As those three leave the room one of the drow gunslingers speaks and says “The last time we fought we were only interested in the stone. But this time you're going to DIE!”
Grim advances and fires and errent arrow at the drow, Turk, who flanked them gets a hit in one one of them and lorath casts slow on the group causing two of the drow swordsmen to drop one of their swords and fire hand crossbows at them, one shot poisoning grim and making him fall unconscious. Shelldon and Colossus advance and begin to strike at them and Eblynn casts a fireball illuminating the room and burning many.
After a few moments the group begins to gain the upper hand but not without taking some significant damage themselves when everyone on the battlefireld is striken all at once by a sickly sinister voice coming from inside their heads which says simply “The Xanathar sends his regards” at which time four bugbear, four kenku, an already enlarged Duregar (who they let leave from the hideout in the sewers) as well as the mindflayer, holding an intellect devourer who they brefily encounterd while recuing Floon all appear seemingly our of thin air surrounding both the party and the drow.
At this point a large and confusing melee ensues which sees the Bregan De'arth Drow, Xanathar's thugs and the party all fighting each other in a brutal battle with shelldon knocking a drow gunslinger unconcious and colossus deflecting their crossbow bolts and lead balls as he charges forward and Turk facing down the Mindflayer who attempts to dominate his mind but he is able ot resist, all culminating in a warhorn sounding nearly deafeningly throughout the room and a gruff voice calling out “Dooooom RRRAiders!” and from the entrace those who are able see see the portable hole which had been thrown down has been collected and a group of four humanoids enter. Among them is Yagra Stonefist whom the party helped in the yawning portal some 17 days prior as well as Istrid Horn whom they recognize as the dwarf recently hired at their tavern and a small shady looking gnome known only to Grim as Skeemo Weirdbottle the alchemist and a very large male half-orc with a gigantic bow. The group of them quickly rush to help Grim and rouse him from his unconciousness. Istrid casts mass cure wounds on all the party which she could see. Hearing the horn, Turk, who is fighting a bugbear and a kenku as well as staring at the now flying mindflayer calls out that a mindflayer is present.
More fierce and fighting occurs with renewed desperation. Turk drops his bow and dispatches with a kenku and a bugbear in a single flurry or swordsmanship as shelldon knocks a bug bear unconcious and grim, now awakened with fury sinks his blade deep into the side of one of the drow's elite warriors and a massive arrow from the half-orc fells the huge dueregar who is attempting to skewer lorath with his war pike.
Eblynn sees what's left of the weary and tattered enemies of what is left of bot the drow and the thugs and casts a fireball which erupts from behind the weary combatants and devastates the small battlefield leaving only a single drow gunslinger standing who is quickly felled.
Lorath attempts to catch the Mindflayer in a web spell but he observes the carnage and casts what Lorath reconices as a planar gate of some sort and vanishes in s shower of sparks.
The Doom Raiders say to Grim that they must leave quickly as they do not want to be around when the authorities arrive but to remember them favorable when the time come.
As they retreat from the room the party searches the bodies and they recover three very curious pistols, clearly of lantanese manufactor. Eblynn finds a fine pair of boots as well on one of the burnt drow.
After some minutes both the blackstaff and lord silverhand return. They say that Jaraxle escaped but that his boats are likley leaving the harbor as they speak and that the message which they were trying to send was at least very sucessful. They ask the party about the vault and it's contents which the party answers truthfully. They react with some surprise and delight at the news that the dragonstaff still exists and head into the vault to speak to the dragon.
