Just something I sketched a while ago and decided to finish after seeing some NiGHTS fanart on Pixiv.
I know Nightmarens are technically genderless, but it's up to folks' imagination to identify their genders-Umbra is definitely a female-not only appearance and behavior-wise, but she refers to herself as female as well. Not much to say about her atm, all I can say is she prefers to spend time in more...bizzare dreams. Dancing that fine line between a pleasant dream and nightmare :P
