The dark cubed

Lore: Nyx wasn’t always a force of darkness. Legends say he was once a powerful enchanter who sought knowledge beyond what was allowed. In his pursuit of forbidden magic, he accidentally unleashed an ancient curse, transforming him into the shadowy being he is today. Nyx’s desire for power now drives him to conquer world after world, pulling each one into a state of eternal darkness. Weakness: Nyx is only vulnerable to Ancient Light Crystals, rare artifacts hidden deep in the untouched parts of each world. These crystals, when forged into weapons, are the only means of breaking Nyx’s defenses and purging his corruption from the world. This should fit the 2000-character limit! Let me know if you’d like any adjustments.
