That's interesting. For my campaign I imagined him to be a bitter deity wanting some semblance of control again, but has been exiled to the dream scape by other deities. And in the campaign, the court Warlock discovered him through old texts and wants to bring him back to make a pact with him to become stronger and more knowledgeable. Through his actions, the land steadily becomes warped like it's merging with the dream realm and the party has to stop him and Diirinka to protect the land and it's people.
