"The gods are not fair."
Thjazi has always believed this, and over the years, his resentment towards them has grown. The gods' disdain for him and his kind has taken a toll on his spirit, to the point that only imparting an exemplary lesson can calm his thirst for revenge.
So, taking the form of an eagle, he heads to the forest where the goddess Idunn guards the golden apples that grant eternal youth to the gods. After long days of vigil, he waits for the opportune moment and while Idunn sleeps, he snatches all the apples from the tree, taking flight with the precious loot to his lair in the northern caverns.
Upon awakening, Idunn falls into despair upon seeing that no apples remain on the tree and that it, along with the rest of the forest, begins to wither. Using all her power, she tries to restore the golden apple tree, but only manages to postpone the inevitable.
Knowing that she cannot leave the forest if she wants to prevent an imminent catastrophe, she uses the little power she has left to endow a small slime residing near the tree with the ability to alter its being, borrowing the power of the 4 elements of nature. With this act, she entrusts it with the mission to embark on a journey to retrieve the stolen apples and restore the tree and the rest of the forest.
