Eternal Flame.
The Eternal Flame (also known as The Eternal Flame of Destruction) is an inextinguishable flame. It is kept in the Asgard weapons vault under Odin's regime. Engraved above it, in an ancient language, are the words "Tuning Fork".
Trivia[]
- In the comics, the flame was stolen from Surtur by Odin, Vili and Ve Borson at the dawn of time so Surtur could not light his sword and bring about Ragnarök.
