It's quite possible that Toksa killed the lolodin (although the phrase about the wild barbarian doesn't quite fit him, but that's probably a clue). But who did we hang yesterday then? Definitely not a dwarf. Another one of the orcs? But who went second for the potion if there were three orcs yesterday? Someone from the city, but not the guardian?
