Hi! I'll try and answer as many of these questions as I can :)
1. There are no Deer anthro period, even though a cute deer girl would be nice. It's Oakridge, and also the greater Anthro world's, primary food source.
2. Yes! There are scalies, but they are few and far between + aren't seen much during the day (although MC might meet one in the future)
3. Probably not, as I'd like to keep the story as grounded as possible. Bree/Goblins will likely be the only 'mythical' addition to the story (although your idea about wendigos is super cool!)
