Exposure to the chill of the life draining winds of Q'Gurth Toa Kive, the magics of both the Ice Maiden, and the enchanted metals of the bones of Fire Demons, you have the residual remains of many old magics of this world. 

Upon your last return back from this particular March, a single snowflake returns with you. It seems to generate it's on cold aura to stay frozen. It carries with it some properties of the land and when you return to Q'Gurth Toa Kive. As you spend more time in that world, you become imbued with more of its magic as it spends more time there.

Currently you have resistance to cold damage and frostbite damage (unique to Q'Gurth Toa Kive).
