Sesehset

From Tardis Wiki, the free Doctor Who reference

Sesehset, later known as Sesehaten, was an android that believed it was an Egyptian priest.

When Ace met him, Sesehaten was a scribe for the nobleman Sedjet. He had been a priest of Set, but changed his name when the worship of the god was banned. In actuality he was an artificial lifeform created by the Ants that could open and stabilise space-time rifts. (PROSE: Set Piece)
