Item, Wondrous Item, Requires Attunement
This large, translucent red heart is fashioned from a magical gem of some sort. It radiates heat in a wide radius, but never grows too hot to the touch.
While you are attuned to the heart, you have resistance to cold damage. All creatures within 30 feet of the heart are immune to the effects of extreme cold, as described in Chapter 5 of the Dungeon Master's Guide.
