The Bifrost was an escarpment on the planet Harvest that cut southwesterly across the Edda super-continent diagonally. It was stated by the AI Mack that the Bifrost was the only major change in elevation on Edda.[1]


  • The Bifröst is the rainbow-colored bridge connecting Asgard to the Human world of Alfheim, it is located after the Plain of Ida. This is yet another Norse Mythology allusion in Halo: Contact Harvest.
