Jormungandr is the world serpent of Norse mythology, the enormous child of Loki said to encircle Midgard with its tail in its mouth, destined to face Thor at Ragnarok. The name has resurfaced in modern games and fantasy media, which is why serpent-themed stings like this one circulate on soundboards. With no confirmed original scene attached to this clip, it lives as a flexible dramatic effect, borrowed by editors whenever a moment needs ancient, monstrous weight.
