Aurinax the Gold Dragon and Banehammer Dwarf

Aurinax the Gold Dragon and Banehammer Dwarf: D&D Collector’s Series Waterdeep Miniature – Rules of Play says:

Aurinax is an adult Gold Dragon. He often assumes the form of an elderly gold dwarf named Barok Clanghammer, who uses the dragonstaff of Ahghairon as a walking stick. This was given to the dragon by Dagult Neverember, Open Lord of Waterdeep and has the power to prevent other dragons from entering the city, until such time as Neverember or his appointed vassals removed it. As it happens, no on has come to remove the treasure, and the faithful Aurinax has remained in the vault. The vault is warded against scrying magi, and there’s no one left in Waterdeep who knows about Aurinax or the whereabouts of the dragonstaff.
