Bill Cipher

After Stanford and Stanley finally managed to defeat Bill, the triangular demon recited a series of words backwards before fading into the void. The words, charged with dark power, were an incantation to ensure that he would be "revived" again. But first, he had to address the Axolotl, the all-powerful keeper of cosmic secrets. Without any difficulty, the Axolotl brought him back into existence.

Upon awakening, Bill found himself in an unfamiliar place, a sort of interdimensional purgatory meant for the rehabilitation of powerful beings. This place was filled with creatures of great power, though none on Bill's level. The atmosphere was heavy and filled with ancient energies, with endless corridors and rooms filled with mystical gadgets. The walls echoed with whispers of ancient deities and demons, all seeking redemption or a second chance.
