Hi there! Welcome to the community.

Honestly I don't really know what to say, hah. A lot of the community does in character stuff like roleplaying and making biographies for our deer. But it's also fine to play an OOC deer! Most people have one even if they have characters.

My suggestion would be to share some art or something. You can also just have a look around at all the things here and see if anything suits your fancy! Like I said before, there's lots of roleplay and character stuff. I'd personally recommend delving into the surprisingly rich fantasy world many players have collectively created by turning your deer into a character, or making a new one for the purpose! But you can play how you like.

If you need help with anything specific, you can ask almost anyone, in addition to consulting these handy dandy links:

These are really useful, though I'm sure you're pretty knowledgeable on forest stuff since you've been in it for some years.
