The trees appear normal and Borek isn't spawn, which enough evidence to get me to stay long enough to wait and see. But Chaos is not a toy and a chance of spawnhood is not to be chanced.Theres quite a lot of evidence suggesting Morghur doesn't have a corruption aura, or if he does, there is a lot of energy invested into ensuring that what it does is being undone
Nevermind the very real potential of quest end in a horrific way, no Mathilde means no RoW, MoD, or chalice.So fun things like "everyone dies" or "your word is worthless" if the witch gets away. There is no replacement for Mathilde's capabilities on this expedition, act accordingly or knowbody will learn anything about KD.
