Apocalypse: Eternal-Class Necromancer

One fateful day, the world was plunged into an abyss of pandemonium. Gateways to other dimensions opened, unleashing unspeakable horrors that rendered conventional warfare obsolete. The mightiest weapons – bombs, guns, tanks, and even nuclear deterrents – were rendered impotent.

If the ancient deity awakens, doom awaits your world!" "Time remains before the dead god's resurrection..." Lucian Morgath couldn't believe the turn of events. He wished he'd never stirred from his slumber. What challenges, and perhaps horrors, awaited him now?
