I have an amazing idea for my character, possibly and elder. I am basing her off a specific person/goddess though. [url=https://en.wikipedia.org/wiki/Marzanna]Marzanna[/url]. What would I classify her race as? Deity, demon, Psychopomps, Nightmare, Spectre, Death, Reaper, Baku, Alp, Banshee, Succubus...?  idk

I'd call her a daemon; it strikes a sort of middle ground between the ideal of a classical deity and a lesser spirit, and they are the figures from which post-classical European faerie myths were derived.
