In a blink, I found myself in an unknown land, greeted by the textbox of an unfriendly system. It wanted me to become a great hero, save the world, win the love of the people and all that crap. But this new world already had a hero. Why should I bust my ass, deal with dragons and the unknown, for people I didn't know? Let him deal with that. It's his job! So instead of being tempted by the system's nonsense, I chose a simple class. Potion maker. I wasn't interested in cultivating mana and defying the heavens, courting death, none of that crap.

After the death of a grandfather he never knew, Caleb Holdstock inherits a mysterious mansion. The place needs a lot of work if its to be liveable, but the truly strange thing about it is what's in the basement. A doorway drawn in chalk.

With knowledge of a magical world beyond Earth, Caleb's life will never be the same again. And the best thing about it? He can travel back and forth freely.

That all changes one night when his old flame, who escaped the village to become a mage’s anchor, returns. Ard’s life is about to go through some dramatic changes, and he’s not ready for them.

There, with only his paladin's sigil and his quests to guide him, Darren grew from boy to man. Born in fire and blood, hell itself sculpted the perfect paladin.

The last thing I remember was being cryogenically frozen, but now I was in a strange room, surrounded by advanced technology I had never seen before. My confusion only grew as I explored this new world–a future that was nothing like I ever could have imagined. It didn't take long for me to learn that humanity was extinct and that I was now in the hands of a stunning AI, a siren with camouflaging powers, and a monster girl who happens to be a great engineer–beings that are as fascinating as they are strange.

Rune Tellarus always wanted to become a Guardian: a powerful warrior bonded to a magic-wielding woman known as an Adeptal Mage. Except he failed the test as a youth.

Randold, better known as Rand, was no ordinary individual. Despite his best efforts, he possessed an extraordinary secret—he was a Super. Well, technically speaking, he belonged to that exceptional group, but he concealed his true nature from the world.

The consequences ranged from imprisonment to something far worse.
