Eberron, Beneath the Temple of Kha'shazul

Three of the well shafts connect the Temple of Kha'shazul and it's underground secrets.  Two young black dragons guard a treasure owned by a long deceased dragon.  There's a lot more to this dungeon, but I'll let you discover what all happens here in the Eyes of the Lich Queen adventure module published in 2006.  Please feel free to comment and adjust as you need.  Enjoy!
