Demon invasion.

So, here's my story. I epically killed the blue player, collected artifacts, leveled up, and... DIED. Glory to NIMUS, he killed three players, including me. His berserker and huge army defeated the Dark Messiah Sigrif! The world is saved... Or not. I cheated and summoned legions, then killed Nimus. It seems I can't win fairly here.

Nimus had 10 archdemons, 22 imps, 40 something horses, etc.
