Vigrond Highlands

The Vigrond Highlands was a area near the city of Utgard on Harvest. Upon the attack of Harvest by the Covenant ship Rapid Conversion, refugees from the small settlements in Vigrond Highlands fled to Utgard, the capital of Harvest.

Trivia
In Norse mythology, Vigrond is a giant plain where Ragnarok, the battle between the gods, will be fought.

Many of the names given to the citys, seas, and other places in Halo: Contact Harvest have been plucked from Norse Mythology.
