Kiinirit eggs appear at the base of trees, and only one of them will appear per tree. There is no way to predict what tree will spawn a Kiinirit egg.
Kiinirits are a type of nature sprite that are intrinsically linked to their trees. Kiinirits will protect their trees as well as any surrounding trees. Some tales say that Kiinirits are a manifestation of the souls of trees. Other tales say that Kiinirits are a type of forest fae. Whatever Kiinirits truly are, they are definitely magical in nature.
