World of Darkness Mummy (2016)

From the introduction:

In the sands of the kingdom of Khem, in times long forgotten, a war began. The lands were ruled by the Pharoah Osiris, and his wife Isis. Osiris's brother Set coveted the throne, and for his machinations was banished. Thus Osiris ruled benevolently over his peaceful kingdom, that is until a stranger came. This stranger, named Typhon, arrived wishing an audience with Osiris. Osiris accepted him and spoke of a coming darkness and war. Typhon and Osiris met on the eve of the full moon for four months. On the dawn after their fourth meeting Osiris was discovered ill and near death, pale and bloodless on his chamber floor.
