Her mother had always wanted to save him, but could somebody as fundamentally broken as Kirei Kotomine even be saved? Ruby wasn't sure, but that didn't mean she wasn't going to try.

The ashen one expected to be consumed with the rest of the world when the darkness came. Now however he and the Firekeepr must find their way through a corrupted and rotting world. Even throughout the ages, the darkness of man's heart will always remain the same.

Ruby should have died that night. She should have died, making the same mistake as her sister. Yet, she did not. Her fire, reduced to an ember in the dark, endured. And, as long as there are Embers, Ash will seek them out. Saved by the Ashes of a long forgotten age, Ruby is now left looking after an old knight, the last of his kind. What adventures will this new bond bring forth?
