nymphs or 💧mermaids💧?
I'm a Sylph of Mind with Polynoe as my denizen, whom my copy of the Theogony translates as "richness of mind." She lives underwater in the center of my planet and controls the many rivers that flow across the land. Her name isn't mentioned outside of lists of the 50 Nereids, which gives plenty of freedom in using her as a character. (I think of the Mind aspect as choices/options/decisions more than logic/intelligence/justice.) What kind of sweet loot do you think she could bestow upon me?
