From Ardrana

Antos is a human mage who works with the Facilitators' Guild of Hanmer. He is noted for being rather short, having bright reddish-orange hair, and for wearing a pair of dark spectacles -- apparently a magical device of unknown powers -- nearly all the time.

His history with the Facilitators is sketchy, but he was apparently considered worthy of being entrusted with an important mission. Specifically, he was recently charged with transporting an item into an underground labyrinth for destruction, but soon there was suspicion that the item should not be destroyed. He accompanied Mace Nighthammer to Jar-Kahn to investigate it further, but betrayed his companions and, with the help of Ildrevan and another mysterious figure, stole the item he was transporting and fled on a ship.
