Pharaoh Pen-abw's Twin Caskets

Origin
Pen-abw (Also known as Elephant) is the provisional name of a pre-dynastic ruler, however since carved inscriptions and ivory tags showing his name is lacking any royal crest disputing the existence of the king. It is said that Elephant was a local king who ruled at the region of Qustul since his name is inside a royal serekh, an important type of heraldic crest. Hieroglyphs found inside an ancient tomb seemed to describe a ritual that Pen-abw forced a slave to lay in one casket while he laid in the other. The ancient writing didn't explain why this happened but the final image is of a Pharaoh with light coming out of him as if renewed.

Effects
Transfers the life energy from the second casket into the pharaoh's casket granting longer life for the pharaoh. Heals and reverses aging for person in first casket, kills person in second.
