Horemshep

 was an Egyptian priest during the reign of Amenhotep II and Erimem.

He made an alliance with the Mitanni to kill Amenhotep and his sons, ensuring the remaining heir was married to the Mitannite princess, Miral. (PROSE: The Coming of the Queen)

Horemshep discovered a stasis box that had fallen to Earth. Upon opening it, he discovered its Erimem, a young female who stood to be crowned Pharaoh, and her mentor, the chief of the royal guard, Antranak. He and his military ally Yanis cooked up an alternate royal succession and gathered an army of mercenaries to make it happen.

Ultimately, the Fifth Doctor and Erimem were able to contain the priest's stasis box entity, and in so doing to fully reveal Horemshep as a villain. Though he tried to claim possession by the entity, Erimem did not believe him, and ordered Antranak to carry him back to Thebes in chains. (AUDIO: The Eye of the Scorpion)
