Howdy dere, Dappleclaw.
To change your home, you can either click on the feather icon in the bottom right corner of your screen (when you're ingame), or you can press B. Doing either of these things will pull up your Bio. Click over to the "home" tab, and from there you can Reset Home (which will put it back to Bonfire), you can Go Home (which will take you to wherever you have your home set), OR you can Set Home (this feature sets your home to your current position in the game). Hope this helps. c:
