"Thorax, stay there!" he yelled, holding his hand up "Just stay there!" His mind raced, possibilities building on possibilities. None of this was possible; none of it could be possible. Not without magic. But if it was magic, why wasn't his armour reacting? Unless... 'I'm going mad.' The thought came unbidden. Perhaps he had been leading them in circles, perhaps he was gone an hour when he had thought he spent fifteen minutes, perhaps he did just imagine the river in place of the ravine. The alternative didn't bear thinking about. Now thoroughly spooked, he backed away again, this time keeping Thorax and the ravine in his sights.
