my point on priscilla was based on the earlier assumption that "Sins" were basically only what was considered an affront in the eyes of god. such as attacking someone un-provoked, such as petrus. priscilla is a special case though and can't be thought about in the same way. her existence, in and of itself, is an affront to the gods. this is made plain as day. how and why she is in ariamis is debatable, but we know its either because gods put her there, or she went there as a means of escape. either way, the gods as a whole do not approve of her existence. this is made clear in the games dialogue and various item descriptions. but even though her existence is an affront to gods, killing her is tantamount to sinning. these 2 things cannot over-lap without a severe amount of hypocrisy. thus, it was my point that it is a sin due to her parentage, most likely gwynevere or velka. which it is, we can't be sure, but all in all its the most plausible situation, but thats been discussed elsewhere.
past this is complete conjecture, based around the above.
whichever it is, they had priscilla put there (or had her run there) to stop the rest of the gods from killing her for no real reason. thus, the gods had no reason to kill her anymore, and the opinion of the gods became neutral. if she isn't a threat, they don't care. due to this, there are more gods that care for priscilla than those that wish to kill her, tipping the scales so that killing priscilla is an affront to the gods.
and this is just total conjecture on my part, with very little basis.
its possible gwyndolin felt a type of kinship for priscilla. i know this sounds like
, but hear me out. first, they are both related to the gods somehow. for gwyndolin, its that his parent is gwyn. for priscilla, gwynevere or velka. whatever the case, they aren't strangers to eachother. especially if gwynevere is the case. this would give gwyndolin even more reason to like priscilla. second, is that they are both misfits. gwyndolin has his tentacles, female-proportions, and the incorrect type of magic for his gender. for priscilla, she is half dragon, and the only one to boot. they are both somewhat unique existences. this would have a high chance of sparking some kinship. at the very least, they wouldn't straight hate each other. the last is that the painting for ariamis is so close to gwyndolin. right above him, in fact. this way, he could stop anyone he wanted from getting in, if need be. the only reason he let the CU in is because he probably didn't think you were a threat. the painted world is not kind, contrary to priscilla's beliefs. or at the very least, not kind to us.
anyways, this is totally
. who would pardon you is oswald. gwyndolin doesn't judge, he meets out punishment. sin, as we all know, is velka's domain. and as far as we know, velka could be anything from incorporeal to the crow that ferrys you to and from asylum. theres way too many theory's on that one. how does one kill something they cannot possibly understand?
