Atum
From Tardis Wiki, the free Doctor Who reference
Atum was an Osiran (COMIC: Old Girl) and the creator god in Egyptian mythology. At sundown, the god Aten became Atum and led old kings to the stars from their tombs. (PROSE: Wardenclyffe)
When the Tenth Doctor borrowed a scepter for Anubis, he convinced Sekhmet to "square this" with Atum and the Guild of Aged Souls. (COMIC: Old Girl)
