Crows on the Skulls
Sarcana the Anti Ghaele
One being in particular was horribly twisted by his addiction to Primordial Magic. He was Sarcana the Anti Ghaele. It was his influence that originally tainted the magic springs beneath the surface of Ayodya. Ultimately he is responsible for the Drow, Duergar and many of the evil magical beasts that threaten the surface races even now. Only the gods are aware of this fact however, and if Sarcana didn’t return to Ayodya recently his name would not likely be known to any mortal living there.
