For a time, she and Dou-Bral shared the portfolios of beauty, love and the arts, and were worshiped by the early Taldans, until at some point they argued, and Dou-Bral abandoned Golarion for the far dark places between the planes.
When Dou-Bral returned to Golarion, he had become the god of mutilation, misery and torture: Zon-Kuthon.[1] Believing that Dou-Bral still existed within Zon-Kuthon, Shelyn reached out him, but he pierced her hand with his black nails. When Thron, their father, tried to welcome him, Zon-Kuthon captured and tortured the wolf-spirit beyond recognition.
One myth speaks of how Zon-Kuthon first came into conflict with Abadar, the god of culture, wealth, and stability. Seeing the crimes Zon-Kuthon committed in Golarion, Abadar knew that he must be punished, and made a bargain with the evil god. Zon-Kuthon agreed to go into exile on the Plane of Shadow for as long as the sun hung in the sky in exchange for an item of his choosing from the First Vault. This imprisonment was not meant to be over as soon as it was, though, and when the sun stopped shining upon Golarion during the Age of Darkness, Abadar reluctantly honored the deal, giving Zon-Kuthon the first undead shadow, which the Midnight Lord has used to craft evil creatures in his realm of Xovaikain ever since.
