After the collapse of the known world, Rowan Wilder opened his eyes and found himself on the first floor of the Tower. With a flawless memory and a mere eight cards to his name, he must venture out and prepare himself for the coming calamity.

Due to unusual circumstances, Randidly starts in an isolated dungeon far beyond his level, forced to rely on the mysterious Traveler Shal in order to learn and survive with the dangerous new status quo for his world. But survive he does, only to leave the dungeon and discover that while he experienced several hellish months in the dungeon, only half a day passed on Earth. Randidly's capabilities are now more than enough to help build a small enclave of survivors, but that doesn't mean balancing his sense of responsibility against the plots of an unfriendly town will be easy.

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.

Damien nearly ended the world. Now, his mistake might be the only thing that can save it. Good things come to those who wait. Damien Vale didn’t, and he ended up bound to an Eldritch creature from beyond the reaches of space. It has lived since the dawn of time, seen the world born and destroyed countless times, and wants to be called Henry. Unusual companion or not, Damien was still determined to go to a mage college and study magic.

Callum had seen things all his life. There are monsters and beasts living among people, but he learned very early not to admit such things, not if he didn’t want people to think him crazy. It turns out that the supernatural is real, but at 30, Callum has no desire to be part of that secret. Not that he has a choice when it turns out he is a mage, albeit one that hasn’t cast any spells in all his life. There are requirements, duties, and education that the powers that be insist he be subject to. To hell with that.
