Thanagar and Pharoahs
In 1500 BCE, there was a brief but violent clash between Asgard and Thanagar, resuming their ancient interstellar war.
A scout ship was shot down.
It was found by Teth-Adam, the royal Prince, next in line to rule unified Egypt and Khandaq (married to pharoah's daughter). With him were Khufu and Chay-Ara, the Prince of Egypt and his beloved.
Khufu and Chay-Ara use the Nth-metal to make wings and weapons, allowing them to fly swiftly over land and fight alongside the immensely powerful Lord of Khandaq.
Teth-Adam later discovers that they were framed by his own high priest. Remorse fills him and he petitions Isis for forgiveness to undo his mistake. She convenes with Nabu the Wise and it is agreed that the spirits of the two lovers should not be released to Endless_Death so soon. The dark god Seth, pleased with Teth-Adam's violence, interrupts the ritual. This binds the spirits of Khufu and Chay-Ara on a cycle of endless rebirth and misery, spanning both Earth and Thanagar.
