Teleporting randomly was not a good idea, especially considering how dangerous the situation was already. As such, when Lex detected the incoming danger, he immediately locked onto the only familiar point: Fenrir's location. Due to their connection, Lex could always feel where the pup was and summon it to himself, but usually he could not do that in reverse. This time, using the In-Law effect, he managed to do just that.
The moment he reappeared he found himself, not in the pool of blood, but in one of the empty halls.
That was all he had time to do before he felt the change. All sound was muted. It was as if the air itself had vanished and the world itself stopped vibrating.
Feeling his sense of dread rising, Lex immediately dismissed Fenrir and let it return to the Inn. The world suddenly turned black, and Lex could see absolutely nothing, even with his left eye.
