Rolemaster - Shadycreek
Jaysek is god of Visual Art and Magic, twin brother of Kieron—and like his brother, he is lean and beautiful. He wears black or grey garments, and has been depicted in paintings, on the Windblessed Coast astride a dark horse, wearing a black, hooded cloak and speaking dark prophesies. Jaysek composed (or has claimed to compose) many of the modern alphabets. He is the patron of Illusionists, Mystics, and Seers, and his favoured weapon is the Kynac.
Kieron and Jaysek: The twins, temperamental polar opposites, nevertheless complement each other. More than one Windblessed Coast culture believes them to be a single deity with a dualistic personality.
