Welcome to Feralheart!
It's good to see you got around to playing it. I would start in The Grounds, that's going right from Lonely Cave where you first spawn then up the path from there. c: Have fun!! <3
A huge welcome to FH! The Grounds is the main "hub" of activity :) You'll find most people spend their time chatting or in private maps in roleplays. In The Grounds you'll find "movies" where people advertise for their RP groups!
(Private maps are maps that are player-created and need to be downloaded to view.)
Hope to see you around sometime!
