Its pitch darkness was enough for the people to call it the dead's land, it was associated with the Styx river that was said to be the boundary between the earth and the underworld.
But before that name came the Stygian City was opposite of its name. It was a beautiful place said in history books with its lush fields and abundant mana suitable for every mana user. That every monster that was said to have resided are friendly and can be tamed. It was because of the pure mana inside the city walls.
And because of this, the dark users and the other affinity users tried to covet it a thousand of years ago from the elves, who were the one protecting the City. It's the reason, elves become much more secluded as time goes on.
They hated the humans who tried to covet what they're protecting.
