The people worth mentioning are the ones who kept being more active in the project, and one of them was Lucas. A British guy, whom you might know better as the guy in a wheelchair.
He was a redhead with a thick beard, and hair on the longer side, which clearly needed a hairdresser's intervention. It's kinda hypocritical of me to say that because if not for Celestine, I would probably look similar.
Lucas used to be a firefighter, but during one of his mission, as he was escorting people out of a burning building, part of the ceiling collapsed on him, and his back got broken. Despite the best efforts of available medical experts, he wasn't able to walk after the accident.
