Galgalia

Galgalia is a high gravity planet with an irradiated surface which was in UNSC controlled space during the Human-Covenant War.

History
This planet is home to the wreckage of the UNSC Firgate Deadalus, which crashed and scatterd debris for kilometers from its point of impact. A handful of Marines survived the crash of the Daedalus by strapping themselves into four M12 Force Application Vehicles. The Marines used the Warthogs to desalinate the water from the planet and were eventually rescued by UNSC forces after months of broadcasting a distress signal.
