NOTE: This is NOT canon to the Birthders unless robertthecogman and/or bb64fam say it is. There's a big text block coming up, but PLEASE read it. It provides very important context. While the Caketaclysm marked the near-end of the Birthders and (eventually) the conclusion of the Birthder Universe as we know it, we all know that when one saga ends, another will take its place. Between the events of the Caketaclysm (plus the Birthders being turned into stone) and the reveal of the Skooglewarmp Islands, an ontological rift formed inbetween the Birthder universe and the outside space, which is a void of nothingness. The energy of the Birthder universe was transferred into the void, and from there it spawned a newer, more chaotic universe where gods are unknown and the vast majority of monsters in the universe do not know what lies outside of their temporal standing. The first of these monsters was the Soul "Manymore," or "Eromynam" as it is written. According to the ancient prophecies, this relatively unknown monster was born from instability and pure, unbridled madness. In order to correct this madness and create this class, the Soul Eromynam had to sacrifice itself to make the universe stable so that monsterkind could live there. In past history, the Soul Eromynam was known as "Determinatos," and the monsters that were made by Determinatos were bloodthirsty... but they would not get their meal until the Skooglewarmps revealed themselves, in which the new class attempted to take them on and thwart their plans of reviving the ancient Birthders, but they were eventually defeated and forced to surrender. The losing class became shrouded in mystery for many years, and the Skooglewarmps eventually revived the Birthders, which is what we know happened. It wasn't until the Angelic War between the Angelic Monsters and Xylophice happened that these monsters came back from the shadows, rearing their ugly heads. When Xylophice and the Mixtures were defeated, it was their destiny to revive, or making something similar to, Xylophice, and eventually take control of the Birthder universe. It's going to be a while, however, since the Rebellians, as they called themselves, were inferior in power AND number compared to the Birthders, especially with the Manymores watching over it all now. But one day, they'll be confident enough... right? Fast forward to today's time. The Rebellians have gathered all of their artifacts and created the Soul Hall, where the Soul Eromynam is worshipped and relics are cared for. The hall also contains the ancient prophecies that the Rebellians know as "holy prayers." Under the power of the Soul Eromynam, they would finally venture across their planet and find the deadliest weapons they could possibly use to take down the entire Birthder universe... again. In fact, the Rebellians are essentially the antithesis of the Birthders due to their chaotic origins. They have to get past the Skooglewarmps, however, due to the fact that they humiliated the Rebellians last time they fought, but since the Skooglewarmps have grown old now, it might just be time for the Rebellians to strike and finish this once and for all.
@robertthecogman and @bb64fam made the Birthders and the Birthder Universe. @robertthecogman made the Skooglewarmps also. @ftgftygt made Disquito's original design
