Castrum Fluminis

A Kojin relic. A hidden trove of crystals. Through these tools of ritual summoning, the restored Yotsuyu is reborn as Tsukuyomi─divinity of night and lady of the moon. This being of celestial majesty would rule from on high, and drown the lands of Doma in eternal darkness. Will your light shield Hien and his people, or will it flicker and fail before the encroaching abyss?
