It had been five years since the SCP containment breach, and Bryan had failed. He had gone to the containment facility for a reason, with a goal. But he hadn't been able to fulfill his goal, and now he was alone. His daughter had been being watched by his sister, Bri, during his time in the containment facility, but when he came back and revealed that he wasn't able to complete his goal and that he had left the facility before it was going to explode so he would never be able to complete his goal. After that, his daughter and sister left him, and since then he's been forced into a lonely life for the past five years. One day, he finally decides to go back to the facility, even if it's exploded and even if there are possible things there that will kill him. He can no longer find a reason to live, so he might as well go back to the last place he felt wanted. (SCPs act a bit differently in this book than they do in the actual SCP canon. I also don't know all that much about SCPs or the SCP role play)
