Sahasza Alric'Koren

Sahasza is a Yuan-Ti male, and at one point a partial partner of Group Alpha.
He assisted the party in locating the demiplane of Adair of Storia, asking their assistance in reclaiming a tomb of his people beforehand.
Sahasza and Group Alpha did not trust one another by any means, but their deal was completed to the exact letter, with neither side betraying the other.
