Excalibur was forged by the god of blacksmiths, Völundr. King of the Frost Giant tribe «Thrym» once transformed into a wolf and infiltrated Jötunheimr to steal it. He then threw Excalibur into «Urðr's Spring», a lake at the center of Jötunheimr where it impaled the World Tree and cut off its roots. At that moment, Jötunheimr lost the blessings from the Tree and quickly degenerated into a barren wasteland of frost.
As the roots of the tree retracted to Jötunheimr's canopy, the frozen lake was pulled up along with the roots. Thus the large mass of ice reached the canopy of the world, where the ice dungeon was formed and later fashioned into Thrym's castle, Thrymheim. The great sword Excalibur, after impaling the roots of the Tree, became stuck at the bottom of the ice structure, where it keeps it from melting and the roots of the World Tree from regrowing.
