Death. For as long as humanity had feared the unknown and across countless cultures, Death had been personified and given an identity.The Grim Reaper, Thanatos, Shinigami. Even his own name, his actual real name of Sephtis, was the name of an old Death God and was kindly given to him by his cult worshipping mother who had a fondness for strange and depressing names.
There was a reason he didn't go by Sephtis anymore.
But, even after everything Seth had been through in his life, the thought of Death being an actual person was one that he never considered to be real. He had fought actual gods, and so assumed that many 'Gods of Death' were just that.
People with Divine power posing as the end of all things Himself. Hell, even Seth was sort of doing that as Corvus, as in his strange little cult he had been given the title of a God of Death.
