Yrael would rather not be one of the main pantheon. He'd much rather be a household god, a niche god of bountiful fishing and musical inspiration, venerated by fishermen and poor musicians. Musicians who went into music for the love of the art and not for money are his favorite devotees. All he asks is the occasional sacrifice of the best fish of the day's catch, or for an occasional song to be dedicated to him.

Sunshine would be an apollo-type deity - in the way that her power would have many different little spheres of influence, all of which would fall under the provider/protector role. Abundance, bread, food, warmth, family, protection of the home, sunlight. Her primary devotees would be those who risk or sacrifice themselves for the people they care about, who would murmur a prayer for her protection as they go into danger to protect their people.

Zelgadiss would be the patron saint of knowledge seekers. Librarians and researchers, especially those seeking arcane and possibly lost knowledge, would pray to him for patience and fortitude in the face of discouraging results.
