Muspell

Muspell is a realm that was originally intended to be the homeworld of the Auspah, although no official decision was ever made. Other possible meanings for this term could have been "Zamorak's world" as the elves believed, or the location where Moia went with Zamorak.

The sigil that represents Muspell on the World Gate can be seen if rotated correctly. The World Gate itself describes Muspell as "A world engulfed in flames. It's kind of beautiful."
