Skidbladnir, Frey's magical ship.
Skidbladnir (Skíðblaðnir) is a magical ship that belongs to the Norse god Frey. Skidbladnir was built by Ivaldi's dwarven sons and had the ability to fly through the air and sea with great speed. The planks used to construct the ship are so thin that the ship can also be transported by simply folding it up, much like the Big Banana, a ship which aided Magnus Chase in his journey during The Ship of the Dead.
