Ahmanet's lover was the lover of Ahmanet, who she intended to sacrifice in order to provide Set with the body of a mortal man. However, when Ahmanet's plans for world domination were found out by the temple priests, they slew Ahmanet's lover where he stood.
After the birth of a younger brother left Ahmanet ineligible to inherit the throne of Ancient Egypt, Ahmanet made a deal with Set, the Egyptian god of death, storms, and evil. This involved a blood ritual which involved Ahmanet killing her father Menehetre and younger brother.
Ahmanet's lover was intended to be sacrificed to Set so that Set may inhabit his body, allowing Set and Ahmanet to rule the world together as king and queen. However, the temple priests, Menehptre's guards, discovered Ahmanet's plans. One of the priests stabbed Ahmanet's lover in the stomach with a spear, killing Ahmanet's lover instantly, and Ahmanet was mummified alive.
Ahmanet's lover appeared to not be afraid of the prospect of death, as he was perfectly willing to die for Ahmanet. This may have been a product of the extent of his love for her.
