On the day of his Proving, Apprentice Summoner Samuel Eamon chooses a white rabbit as his familiar, summoning a creature from the Outer Spheres and dubbing it “Snowball.” What he gets is a shapely succubus with bunny ears and a poofy cottontail. Turns out everything he tries to summon ends up a succubus. With his new Summoner’s License, Samuel is sent with a former classmate as his escort to meet Runescribe Elantrica Ilmora—someone who just might be able to discern the truth behind his odd spin on Calling Magic.

The Dungeon is a place of magic and mystery, a vast branching, underground labyrinth that has changed the world and the people who dare to enter its depths. Those who brave its challenges are rewarded with wealth, fame, and powerful classes that set them apart from the rest.

Fight, survive, adapt, and rely only on yourself. That is Derek’s creed and what's got him through the System Integration on Earth. Everything changed when the System came. Cute bunnies and beautiful butterflies became savage killing machines. Then the Invaders arrived with a single goal: to obtain ownership of this new habitable planet. War has raged ever since. None of this mattered much to Derek, aside from making living a little more perilous.

Wanting to go into business with his best friend, Evie, Calon never could have expected how his life would turn in an instant. Rushing into the burning home of a neighbor, the unthinkable happens, and our fearless main character dies a hero. Only...he doesn't quite make it to the afterlife.

It was a day like any other when suddenly the world changed. The universe reached a threshold humanity didn’t even know existed, and it was time to finally be integrated into the vast multiverse. A place where power is the only thing anyone can truly rely on.
