The year is 605, and in your home— the country of Corcaea— the souls of mankind belong to demons.

A phenomenon known as the "Catalyst" is what's to blame. This diabolical phenomenon lurks within every man, woman, and child. It can turn any human into a demon, if they fall prey to one, all-consuming element. It can be anything. Fear. Grief. Generosity. Even love.

In a land where Gods are real and Corcaea's theocracy is the last hope for mankind, you follow in the footsteps of Father Richard Anscham: a troubled young priest, the leader of the Church of Mercy, and the foremost researcher of the Catalyst. Deep-dive into the ruins that cover the land with nothing but your dog and your faith. Search for the cure. Conquer your personal demons.

Welcome to Catalyst Quest! A "quest" is a collaborative storytelling medium in which readers get to vote on the story at specific points. As this is an archive, the prompts that were included with the original run of Catalyst have been stripped, and the story is presented like a traditional novel for your reading convenience. If you would like to read Catalyst in its original format or participate in current events, you can find us here, on Sufficient Velocity.

A new chapter will be posted every day, on a 25-hour schedule.
