Adalon

Adalon is a silver dragon living in the Underdark near the city of Ust Natha. Her task is to guard the drow city and maintain peace between the drow and the elves of Suldanesselar.

Jon Irenicus stole Adalon's eggs and held them for ransom, giving them to the matron mother of one of the houses in Ust Natha. Adalon enlisted the aid of Abdel Adrian and their companions to retrieve the eggs, turning the adventurers into the likeness of drow so that they might infiltrate Ust Natha.
