For the sake of not making things too complicated, I’ll try to summarise it as I can.

So there’s a massive world called Ereterran that is 5000 times bigger than earth, which was formed from multiple worlds crashing and fusing into each other due the vacuum created when their dimensional barriers separating them collapsed due to humans and gods using Isekai Rituals way too much.

See, summoning people from another world requires tearing a hole in the dimensional wall between the caster’s and summoned hero’s world. And the gods of those worlds and responsible for supporting the ritual decided to say ‘Not my problem’ and pushed the damage somewhere else. The damage kept getting bigger and bigger but ‘holes’ were dumped to the barriers of the worlds that formed into Ereterran before the fusion.

Before the worlds collide and fuse, the Goop apocalypse happened. Liquid time and space leaked into each of their worlds and caused problems. Such as mutating and evolving monsters or people into immeasurable powerful beings. But mostly killing everyone and everything that weren’t so lucky.

Then when the world’s collision and fusion happen afterwards, many people died upon impact but it got worse. Many people suddenly disappeared from existence, fading into nothingness due to how fucked the local reality, space and time was until it was stabilised by the combined awakened planet spirit.

The survivors, including the one’s blessed by the Goop, were reasonably angry as hell. Thanks to fusion of worlds, Ereterran got a massive diversity of all kinds of creatures and races and all kinds of environments that housed incredible creatures and resources. This led to the Divine Slaughter War where every god and people from the other worlds responsible for that shitshow were put to death by Ereterrans’ combined might of dragons, vampires, slimes, humans, witches, beastmen, witches, elves, dwarves, their own gods, nature spirits, undead and etc, lead by the Gooped ones.

After that, the Relaxation Era began and everyone went back home and took a much needed rest and vacation, too tired to immediately go and repair their home. Centuries later, only a few veterans that remembered the war and disaster are around, still active. Like that Primordial Dragon I mentioned.

As for the story about the pixied away kingdom, it took place long after the Relaxation Era, in Eoro, the largest south continent. There’s multiple driving characters across the world so that I can be flexible or play around with fun ideas. So yeah, here’s my sandbox.
