Made possible by shinaobi, Magery, Turing, and a whole bunch of others who facilitate my madness. Thanks a whole bunch, guys.

Note: This story is in the process of a rewrite! You can start at the rewritten first chapter here.

The main story beats will remain the same, but the objective of this rewrite is to bring the earlier chapters in line with the actual tone of the story. The further we go, the less should be rewritten. The original batch of chapters will remain, however, if you're into that sort of thing.

The Lighthouse. The Project. The labours of the Department of Astrology. The lifelong work of Director Maris-Billy Animusphere, Lord of the Clocktower and Patriarch of an arcane lineage centuries old. The Chaldea Security Organisation.

Is all that is left. When Incineration burned humanity and its history to cinders, only a handful survived on this lonely lifeboat. And they, they alone, are able to win it all back. In their hands rests the fate of humanity.

Specifically, in the hands of Ritsuka and Kana, twin siblings blessed and cursed with magical potential, now the last two humans left with Master authority alive. A neurotic boy who struggles under pressure and an irresponsible girl who encourages chaos for her own amusement.

Supporting them are a sheltered girl with superpowers, a man being catfished by a Wizard, and Leonardo Da Vinci as a woman.

In this war against extinction, a battle to prove humanity worthy of survival, all hope rests upon an unlikely set of heroes and their ability to wrangle actual Heroes to kill the enemy before they kill each other.

And for better or for worse, they are the twin children of Shirou Emiya and Rin Tohsaka.
