Kaldheim is a plane featured in Planechase, on the card Skybreen.
In Duels of the Planeswalkers 2014 Kaldheim was the location of the ultimate boss, Ramaz.
Planeswalker Angrath seems to have visited this plane, but it is not his home plane. It seems Kaldheim is metaphysically close to Ixalan
- The name "Kaldheim" literally means "cold home" in several North Germanic languages, such as Old Norse, Icelandic, and Norwegian Nynorsk. "Home" means "land", "realm" or "world" in this context, like in Old Norse Jǫtunheimr "land of the giants" or "Giants' home". The word heimr was used along with the word garðr lit. "yard" (as in Miðgarðr lit. "Midyard") in the names of various realms in Norse mythology.
