Tyr's temple
was a temple built by all the races of the Nine Realms for the Norse God of War, Týr. According to Freya, it was the last known action of cooperation between the Nine Realms before peace disappeared.

The Temple is the only way to access other realms of the World Tree from Midgard, though realm access can be restricted as Vanaheim , Asgard and Svartalfheim's acess has been cut off by Odin through unknown means.
