Fimbulwinter
The Fimbulwinter ("Great Winter" in Giant) is the realm of Thrym, King of the Frost giants and Lord of Winter.
From this stronghold and grim feasthall, Nyfhall, Thrym rules a vast tundra lit by glittering icefalls, while the rest of Fimbulwinter is said to be mountainous, but still filled with snow, ice, frost, and glaciers. Thrym is said to roam the mountains and glaciers of this plane, rather than remaining in the Citadel.
