An Isekai story featuring you and a Dark Lord! And a... Lich King?! And a... Demon Lord too?! Oh no. Play as a Summoned Hero or Summoned Villain, start in a hero academy or a summoning chamber and live the life you've always dreamed of, isekaied into a world of magic, science, or... EVIL. The choice is yours!


Author's Note: Welcome to An Isekai Story. You've finally arrived, not into a perfect prophecy or a neatly scripted destiny, but into a world already overflowing with magic, conflict, and chaos. Kavrix doesn’t wait for heroes to catch their breath. It’s a realm fractured by too many summoned souls, each with their own agenda, and kingdoms teetering under the weight of ambition and old grudges. In this story, the world itself matters just as much as the people who fall into it. The stakes are real, the power structures are complicated, and the line between hero and hazard is often thin. Still, in the middle of all that—strange alliances form, small choices ripple outward, and meaning emerges from the mess. Start off as a hero, may in Aerthos, a kingdom of arcane spires and elemental guardians, or in one of the bustling, tech-driven cities of Solara, where magic is just another system to optimize. Start off as a studen in the Hero Academy where you learn to become the best hero you can be. Or maybe you were mistakeningly summoned as the villain... The story is yours you control. Thanks for stepping into the madness. I hope you enjoy the journey as much as I did making it!

Description

The Runeclaw Ursine is a colossal bear imbued with ancient magic, its massive claws etched with glowing runes that pulse with elemental energy. This creature is fiercely territorial, guarding areas rich in magical energy, and its attacks can unleash devastating elemental forces. Legends say it evolved from ordinary bears exposed to powerful ley lines, becoming a guardian of the land's raw magic.
