When none of you leave, she nods and is suddenly all business.
"Alright. This mission is going to all but bankrupt me, but I can pay you, and in advance."
"Aregenyu is one of the oldest Black Dragons in existence. She has a palace on the Elemental Plane of Water. She rules over a brood of other Black Dragons, and only her power keeps them from declaring independence. I want to raid her Hoard."
"I'm not sure how much you know about Black Dragons, but raiding her Hoard will shame her. If she admits something was taken then the other Blacks will fracture away. Logically her only option is to pretend nothing has been taken."
"I've arranged to meet with Aregenyu. I know what she wants, and she's agreed to meet with me. I can keep her - and most of her 'court' - busy for about thirty minutes."
"The Black Dragons are too proud to do their own housekeeping. They enslaved some local Gillmen who do all the cleaning, maintenance, anything that needs hands."
"You'll go in when I do, transformed to look like Gillmen. We'll arrive at the stables. There you'll go through a secret passage that Aregenyu isn't aware of to the Vault. You wait for your transformation to end, then go in. The Vault is kept dry because a number of Aregenyu's treasures would be destroyed by water."
"There you put certain of her treasures onto a pre-prepared cloth and activate a certain scroll. Activating any magic in the Vault should cause it to lock down, but the secret passage will remain open. If a spell doesn't cause it to lock down, then use fire. You take a potion to transform into Gillmen again, go back into the passage, swim back to the stables, and leave with me."
"There'll be seven of you all together. The vault will detect non-humanoids, active magic and fire. I need enough of you to move a few of the larger items of treasure."
"Everyone who goes gets forty pounds of gold. Don't bother negotiating, it's all I can borrow. Aregenyu knows every item in her hoard intimately, has the magic to track them down, and a burning desire for revenge. Feel free to grab any coins in the Vault though - as long as you spend them quickly and discretely."
"After the mission I should - eventually - be able to get anyone who dies brought back, so try to take as much of the body of anyone who dies as you can. I'll give you some acid - use it on anything remaining."
Sense Motive DC 20
fifty pounds of gold = 2000gp, so 2000gp each.
