Thalassocus

A grape-enjoying demigod emperor who got a little too confident in his new found popularity, and when the masses found out he was a lying sham, they were not very happy. 

He was stripped of his power, and before being exiled from the empire, he flooded the palace and stole all their grapes. He wandered around for a bit but eventually he found a nice island to live on where he met a naiad whom he fell in love with.
