After an emotionally and energy-consuming battle against the god-serpent Jormungand, the elves finally got the long-awaited victory.

It was all thanks to the participation of a blood elf in this expedition.

Without Tristan, the magus level elves might have given up and found no way to defeat this terrible ancient monster. They would need to resign themselves to being trapped in that layer for decades, waiting for their descendants to embark on the next expedition to the mist.

After pulling out the spirit soul from the mythical creature, Tristan and the others could be completely sure that the monster had been completely defeated. 

And after the ancient monster was defeated the world within the layer experienced a great earthquake. The shaking of the ground beneath made the giant pillars that became the monster's throne slowly begin to break and then collapse to the ground.
