Serpentine Serxees
Serpentine Serxees is one of the Dark Reign's dark divines.
Many millennia ago, this ambitious and highly intelligent yuan-ti sought to change her culture in its very foundation, realizing her people's way of doing things wasn't sustainable and would cause their civilization to be wiped from the face of the world. One of the ways she nearly achieved this was to whisper sound advice into the ears of rational superiors and probable lies into paranoid leaders.
In her endeavors, she happened upon the corpse of a goddess of her people, and consumed its flesh, ascending in the process.
