Many millennia ago, Trigeth obtained the power of a creator god, and created the ultimate dungeon to punish ambitious mortals. He sat atop the very roof of the dungeon. Right above the 1000th floor where his brother, Nerulhei, became second dungeon lord. Now he awaits another immortal warrior to take the throne and be congratulated by him. But never would he expect you, a mere mortal, to defeat Nerulhei in battle. He has become furious and believes that it is just if he were to kill you.
