Nero was the pope of the church of silence, a cult and terrorist organization as branded by the government authorities. When he was finally apprehended by the police, he was sentenced to death for his various crimes which included terror attacks and mass suicides just to name a few.
As Nero left the world of earth after his gruesome execution, he found that he had been summoned to a new world as a dungeon lord.
Needless to say he wasn't too pleased, though he wasn't too unhappy either as he got another chance to fulfill the main doctrine of his church.
That is, to reap every living being from the world and send them all unto the infinite embrace of the great silence, and he will do so with a fanatical devotion as he raises armies of countless unique undead.
This new fantasy world will come to despair as all life, whether good or evil faces absolute extinction.
