Spoilers for part 2 below

Biography
[Work In Progress, all details are as presumed by this editor]

The King of Grangold is briefly mentioned in part 1, whispered by soldiers about a monster that ignored swords and magic alike, destroying all that crossed paths with him.

In part 2, while traveling, there are occasional glimpses of the King of Grangold battling with the army. Indeed, he ignores mortal blows and retaliates with massive area clearing magic. All without saying a word.

Finally, after having Lazarus open a route to inside the Grangold Castle, he is encountered in the sewers. Both Lazarus and Merlin gun him down and use high tier fire magic, to no success. Then, it seems that for the first time, the King Of Grangold shows his true power, transforming into a magical chimera. To fend him off, Lazarus and Merlin leave the party. Upon reaching Lilith, a short cutscene is played of Lazarus and Merlin talking to the King, before earth magic appears to collapse the area.

After beating up Lilith, and all that's transpires after that, the King of Grangold is freed of his brainwashing and reconciles with Queen Ant, who then both reside in the brick warehouse to the right of the castle, which is under repair from the battle. The first thing Grangold King asks of the party is to take care of the Lady's Village situation, as well as the civil war going on in Succubus Village. He promises to reward the party well, and gives out various unique weapons and a Genji Glove for completing it.

Later on, while Spider Princess alongside the other 3 Monster Queens are attacking various cities, Grangold King appears to be taking a rest. After Luka and co fend off 2 waves of spider monsters, Spider Princess gets news that the Grangold Castle is devoid of people and in disrepair, with the King nowhere in sight. Furious, Spider Princess appears to want to take it out on the citizens, but the camera pans to the brick warehouse, and the door opens. Grangold King takes a single step forward, apparently wanting to enjoy some fresh air. A moment of silence occurs before he notices the spider army attacking, and then he teleports to the right wing of spider monsters and wipes them all out in a single breath. The party is shocked. Spider Princess is also shocked, before also teleporting to where Grangold King is and fighting him. After the party regains their senses, Atlach-Nacha, a mini boss, appears. In the time it takes to beat her up, Spider Princess orders a retreat, and vanishes. Not even a second later, Grangold King appears in front of the party and demands to join, vowing vengeance upon the Spider Princess.
