The Ice Oath is a holiday celebrated on Glacius. 1,300 years ago Glacius died because the Kodar s neglected the planet's Mega-Core, the source of Glacius's power. During the Ice-Oath celebation the Kodars give their energy back to the planet. There also a few missions on Glacius that feature the Ice Oath. That mission has three parts, in which the third part the Kodar has been corrupted by the Swarm.
