Asgard

"Asgard is millennia beyond you in our pursuit of science and knowledge... And we have learned there are some things that can never be understood."

- Sif to Phil Coulson

Asgard was one of the Nine Realms and the home of the Asgardians, a powerful race recognized by the galaxy as honorable and brave peacekeepers between planets

Asgard was destroyed during Ragnarök when Thor ordered Loki to unleash Surtur in order to kill their sister Hela. Led by their new king, a large number of survivors fled onboard a starship, planning to relocate to Earth, in a village they dubbed as "New Asgard." Asgard was later recreated by Ariana Strange.
