Ancestors of the great Irish Sea Serpent (Oilliphéist), Morrigan and Sean, are bound to serve the great Mythical King, Tier, a cruel Leviathan who rules his people with an iron fist. The only way to leave the King's service...is to provide a successor of your own blood.

Morrigan the witch cannot have children and her brother, Sean, the King's Royal advisor, is asexual. They are bound to the castle, never ageing and never changing. King Tier is adamant that Sean must have a child to continue his family bloodline.

Play as Morrigan, who vows to do anything to protect her brother from the King's toxic demands.
