Mephistro

Blackstar was created by the mighty demon Malphas, a great President of Hell who often appears in the form of a crow. Blackstar acts as an agent sent to our world, which died long ago, and now only exists as a ripple of dying light, travelling through the cosmos. We're all just a recording of fading echoes from a dead world. Blackstar harvests the remaining sparks of our souls that still exists, trapped in these ghosts, and feeds them to his creator, so that Malphas can continue growing stronger over the eons and eventually become like God.
