Everfrost is an unexplored frozen tundra to the far north of Erenoth, bordered to the south by the Anvils and Karn. It is inhospitably cold and populated only by giants, orcs, and the like. It is unknown how far Everfrost reaches.
After killing Aeras the Reclaimer, Alazvesh fled into Everfrost and has not been seen in thousands of years. Many theorize that he succumbed to his wounds in the tundra and that his bones lay somewhere beyond the Anvils.
