What is the realm of the Vanir gods?

The story behind the answer

Vanaheim is the realm of the Vanir, gods linked to fertility, prosperity, the sea, and magic. Notable Vanir include Njord and his children Freyr and Freyja. After the legendary Aesir–Vanir war, the two groups made peace and exchanged hostages (Njord, Freyr, and Freyja moved to Asgard), blending their traditions.

By contrast, Asgard is the home of the Aesir (Odin, Thor), Niflheim is the frigid world of mist and cold, and “Aetheria” isn’t part of Norse myth. Memory tip: Vanir → Vanaheim (both start with “Van-”); Aesir → Asgard (both start with “As-”). Vanaheim is one of the Nine Realms connected by Yggdrasil, reflecting a cosmos shaped by conflict, kinship, and exchange.
