Jotunn

The jotnar (singular jotunn) are a race that lives in Jotunheim, one of the Nine Worlds. They are commonly known as giants. They often interact with the gods (both the Aesir and the Vanir tribes), usually in hostile ways, but there have been instances of intermarriage between these races.

History
The first being that came out of the primordial void, Ginnungagap, was a Jotunn called Ymir. His children, born from his armpits and feet, ruled Nilfheim, the World of Ice. Ymir was finally slain by Odin and his brothers, and his body was used to form Midgard, the World of Humans. Ymir's flesh became the earth, his blood – the sea, his bones – the mountains, and his teeth – rocks and cliffs. Finally, Ymir's skull became the sky, protecting Midgard from above.

Appearance
Appearance of the jotnar vary. Some of them may look more human, or have monster-like features – claws, fangs, etc. – or have a completely non-humanoid shape (such Jormungand and Fenrir, children of Loki). However, many of the jotnar can also be indistinguishable from mortals, the Aesir, or Vanir. Some of them are incredibly tall, others may regulate their height, or be the size of a human.
