Lifebound was a type of marriage practiced by followers of the Shake sect in Kurald Galain. The religion was broken into two parts by gender: Yan, Sons of the Mother and Yedan, Daughters of the Father. Sons and Daughters could become lifebound mates of each other. It was not a typical marriage in that it did not require cohabitation or fidelity. It could even be practiced between relatives, such as blood kin and lifebound mates Mother Sheccanto Derran and Father Skelenal. When both lifebound died, they were buried in the same grave.
