The return of the king
After using the inspect skill on the pieces of rubble, Quinn had gained three new shadow skills in the system. He wondered if the entirety of the walls was present, and hadn't been destroyed if he would have been able to extract more information from the room.
Perhaps the system only gave him the skills it could figure out from what was there.
'Some large pieces are missing from the wall. Did Arthur take them with him so they couldn't rebuild it back together like me and Kazz was doing? Which means the other pieces of the shadow might be with Arthur, but why didn't he just put all the pieces of the walls into his dimensional storage?' Some things certainly didn't make sense, and there was always the chance that it wasn't Arthur as well, but who else could enter the fourteenth castle and would know about all these secrets.
