Muspel

Muspel (ムスペル) is one of the world's four Great Spirits, being the Great Spirit of Earth. He was said to roam freely within Vollachia and had settled himself in the territory of House Abellux until he was partially devoured by Arakiya roughly 7 years before the start of the main story.

Although Muspel's current whereabouts are unknown, it is said that his abode is at the Gairahal Tropics, a location near the Fortified City of Garkla.

Personality
Muspel is thought to have no intentions, words, or philosophy, and appears to exist solely as a deific being. According to records, Muspel moves on a grand scale every 12 years, leading to various earthquakes after its movement.

History
Some time around the events of Vollachia's most recent Imperial Selection Ceremony, Vincent Abellux found a method to trap Muspel within his territory. By using Muspel's power, he was able to repel the attacks against his castle ordered by one of his younger half-sisters, Lamia Godwin. Later on, when Prisca's life was in danger due to Lamia's artillery, Arakiya devoured a small portion of Muspel in order to defend her princess.
