Age of Magic Eraser
Erasers are Demons with enormous magical power which they use to weaken enemies, draw out their vital energy and kill them when they are finally exhausted. It is hard to say what developed better in these creatures: their magical skill or their wile.
Erasers are close servitors of the Demon Lords. They do not waste their time on trivia and appear on remnants where the Legion has very serious interests. The emergence of the Eraser on a remnant is a bad sign for its inhabitants.
Eraser uses the power of fire and darkness to control the battlefield and deal great damage to his enemies. Heroes of the past would tell that they had seen how these Demons grow stronger when they feel how their enemies suffer.
