Teos

Teos is a member of the Cowled Wizards of Athkatla, encountered during the events of Baldur's Gate II: Shadows of Amn and its counterpart section in Baldur's Gate II: Enhanced Edition. He serves as a go-between for Gorion's Ward and the Cowled Wizards should Gorion's Ward become the inheritor of the Planar Sphere of Lavok Corthala.

He offers very little incentive for Gorion's Ward to ally with him, instead relying on threats and bravado. Whilst he promises to "look into" the matter of where Imoen is imprisoned, the Mage Stronghold questline ends with him admitting that he has been unable to find anything of use, leaving the player to resort to their own devices to pursue their oldest friend.

Mod Content
In the Enhanced Mage Stronghold mod, he serves as the gateway for the mod's content by attempting to talk the player into opening up the Sphere as the new Athkatla Arcane Academy. He also sends them on a quest to retrieve a lost magical artifact warded by Mystara... which ends up backfiring so spectacularly that Gorion's Ward indignantly expels him from the Sphere forever.
