Sanctum is a Location in Mass Effect 3. Sanctum is located in the Decoris system within the Sigurd's Castle cluster. Locations can be explored while you traverse the galaxy. Locations may vary in size or scope, and may or may not have Missions associated to them. Some of them can only be scanned from atop the Normandy, while others can be landed on.
Sanctum is proof of the old spacer adage, "just because it's called a garden world doesn't mean it's a picnic." Freezing ice storms cover the poles and temperate zones, leaving a narrow strip of habitable land at the equator. Dry but windy, this area is home to Sanctum's minimal terrestrial plant life. The planet has yet to develop land-based animals, though invertebrates grow quite large in its pelagic seas.
Mining, referred to as "ice cracking" at anywhere but the equator, is a common employment on Sanctum. The planet is rich in platinum and palladium deposits, as well as boron, which is locally used in semiconductor doping.
TRAVEL ADVISORY: Carbon dioxide levels on Sanctum can reach 5,000 parts per million during thermal inversions. Travelers should carry a breath mask at all times and consult the Sanctum World Weather Service for warnings.
TRAVEL ADVISORY: Piracy is at a fourteen-year global high on Sanctum. Visitors should take appropriate security precautions.
