This season 7 week 3 epic quest requires you to dance by a lit campfire.

Luckily for us campfires are not some unicorn type item that is impossible to find. They are literally everywhere. I'm not even going to give you a map fo locations because it would be an information overload.

Just play the game and you will come across a campfire sooner or later. Lit it, dance using any emote and enjoy you 30,000xp.
