Eighteen-year-old Callum Stross never asked to become a hero. Struggling through a brutal harvest alongside his father, he's more concerned with surviving the season than reliving ancient wars. But when a devastating aetherstorm strikes, Callum is forced to seek shelter in a cursed manor, where he discovers a dormant Aethercore tied to the bloodline of the legendary Demonslayer. The core fuses with his soul, awakening latent power and binding him to Fen, a mana-bound fox who claims Callum is the Reborn Heir meant to finish what his ancestor started.

The siren has sounded, and old factions of the multiverse are moving. The Earth in general and Silas in particular have become hot commodities. The system was supposed to give Earth a probationary period, but the Invasion is beginning. Silas will either form new enemies or new allies, and the fate of the Earth may rest upon his decisions. With that will come new opportunities and new challenges.

The 42nd Merging arrives, mass-transporting every human to a hostile new world with a System. Everyone must choose a Class, and Quest directives compel them to climb the leaderboards for categories like highest level… and most kills of other people. Jordan isn’t anyone special before the Merging, but the new start equalizes the playing field. He must exploit his versatile class to overcome powerful monsters and opportunistic strangers who kill people as a quick path to power.

For 5,000 years, the Wild Era of humanity has reigned supreme, where strength and magic are the source of everything. Kelin Wildfire, once called the Lord of Wildfire and the Archmage of Souls, was mysteriously killed on a battlefield of the Chaos War. Nevertheless, his soul lived on in the cycle of reincarnation, his memories frozen in time. Until today. Now he is twenty years old, an orphan living on a lawless planet in the human domain where he is barely able to scrape by.

Tad doesn't have any memory before waking up on the beach, apparently the sole survivor of a shipwreck. All he has from his past is a necklace with a symbol no one recognizes. After growing up in the orphanage, he takes a job managing inventory for a merchant catering to adventurers. He knows he's a bit off, the world just smells different to him. When he's confronted by a group of adventurers with more power than ethics, he learns that it's been magic he is smelling all along.
