Ásbyrgi: Thor, trying to prove his strength, challenged Sleipnir to a race. Odin agreed, but secretly fed Sleipnir his favorite snack, lightning bolts. With each step, Sleipnir left a massive print, and thus, Ásbyrgi was formed.

Dimmuborgir: Loki, the trickster, held a housewarming party for the trolls and elves in Dimmuborgir. He spiced the food with a touch of mischief, causing everyone to break into spontaneous, ridiculous dances that lasted for days.

Hekla: Freyja, the goddess of love, hosted a witches' convention on Hekla to improve their matchmaking skills. The witches accidentally brewed a love potion so powerful that it caused the volcano to erupt with passion.

Elliðaey: The skoffin, tired of its isolation, devised a plan to hitch a ride off the island. It disguised itself as a mythical creature tour guide, successfully luring a boat full of curious tourists to Elliðaey.

Mývatn: Balder, the god of light, organized a contest for the supernatural beings of Mývatn. The prize was an all-expenses-paid vacation to sunny Valhalla. The competition was fierce, with participants showing off their most impressive magic tricks.
