Yinkin is the god of alynxes.
You cannot directly build a shrine or sacrifice to him, and he gives no blessings. You may encounter his priests during events though.
You may wander into Yinkin's Wood in the godsplane, if you get lost during a heroquest.
One of Kero Fin's sons, Yinkin is Orlanth's brother, and maintains a close friendship with his nephew Odayla.
