The Ðern is a very popular dude in folklore, he is just a chill fisherman dude, and will help you find your way if you get lost, but you must have a fishing rod with you.
Nobody knows if he is real, this heatmap shows where he has been reported.
Many people who had gotten lost in the Axolotlian wilderness and had a fishing rod claim to have found their way home with the Ðern’s help.
One guy, William Walker said “I’d gotten meself lost up in the Central Mountains, made meself a rudimentary fishin’ rod with a vine and a stick, then the Ðern show’d up and led me my way home.”
