This is a bad guy! Listen:
"His heart rocked by a storm of desperation, the young Prince climbed to the top of the Worm Mountain. Determined to end his life he threw himself into the boiling gorge of the Worm. He was received but not destroyed. The glowing spark of hate and anger in his heart ignited a long smouldering fire inside the creature that once roamed the world to devoure it with it's flames. The Worm saw it's chance, it could feel the third seal fading. The third seal had always been the weakest but now it substantially trembled. The heavenly bodies stood favorable in the sky and the Worm decided to wager.
It gave new life to the Prince and clad him into a magic armor. This strained the Worm and by gathering it's last bits of strength it forged a mighty weapon. This weapon contained the Worm's fiery odem and it was hardened by the icy light of a blinded sun. It was able to overcome the spell of the three Worm Seals and emerge to the surface. The Worm was exhausted and had to rest.
The flames died on the top of the Worm Mountain and the people, who did not know about the baneful events, thought this to be a good omen. But at the base of the mountain the earth split open and the Firelord rose to being. His dark minions administered to their new master the burning Worm Axe, the blade that contained the odem of the beast. After being banned for centuries the Worm had finally found a way to creep back into the world. And even if now he was exhausted and fallen asleep, the forces of evil were unstoppably seeping out to prepare his awakening once again."
