I have a sweet spot for Dryads and Nereids as well as Elements and their kin. Looks like I'm pretty spiritually inclined. ?
Not a single one of those are hybrids though. Every one of them are the spirit or incarnation, meaning it's not combined with anything.
Dryads = spirit of a tree.
Nereids = spirit of a body of water
Elementals = an apparition, embodiment, or incarnation of an element
In my case, I tend to become fascinated with all the branching sub-types of elves, because there are quite a few lesser known sub-types, and I have even taken that to the extent of cross-breeding them.
In AD&D there was an elven sub-race known as grey-elves. In AD&D, they were their own race and not a hybrid, but they weren't really picked up by anyone. The only elven sub-race anyone these days seems to know about at all are dark elves. So, I decided, fine! I'm going to re-introduce grey-elves as a hybrid race of light elves and dark elves. Makes sense, right?
