It is said that in the dawn of time, when the gods still walked among mortals, there existed a mystical substance known as the Grease of the Ancients.
This enchanted grease, imbued with the essence of the land itself, was said to hold the secrets of the universe within its slippery confines.
Many sought to claim it, but few succeeded, as the gods themselves guarded the Grease with an army of razor-toothed, oil-sucking Gristlebeasts.
