I made his reference sheet a long time ago, perhaps I will update it soon.
But he's a grumpy old forest spirit with no gender or (known) age. He DOES go by 'he' but only because he was called by 'he' from he start, so he has gone by a male appearance since.
He pretty much IS a guy at this point. lol
He does have a 'human' and 'furry' appearance, bu I'll get to it someday. lol
