Geasa (singular geis) are rules, requirements, and prohibitions written into the fabric of Fate. This Purview binds the Tuatha and their Scions to geasa of their own and lets them lay geasa on others. It can influence the behavior of those under a geis, granting the power to uphold them or tempting Gods or mortals into breaking their geasa.
Innate Power: You are under a geis. If you break it or otherwise resolve the Condition, the Storyguide should arrange for you to fall under another — either from a Tuatha or fellow Scion, one of the sidhe, the biting words of a poet, or simply mythic circumstance. You take on a second such geis upon becoming a Demigod, and a third upon becoming a God.
