I love it, honestly. It's a fun name, though I'd do a double-take if someone actually used it for a kid. I named a dragon character this under some mildly... well, more than mildly embarrassing circumstances (there was one song, Lothlorian, by Enya that I really loved, didn't know anything else about her, but loved that song so much). As such, it's hard for me to remember the whole 'war hungry war goddess' thing, which is a little sad. This name is honestly really cool, in my opinion.

I was looking at another goddess Angerona, and found that the root of her name, anyo, sounds a lot like Enyo. Angerona means "to strangle" or "to torture" so Enyo could mean the same thing.
