Not sure how that would be done (maybe breaking the warding pottery, hence broken Gelmorran potsherds), but it would explain the enmity between clans if that were an ancient Duskwight's perspective.
Honestly, so much is uncertain surrounding Duskwights that you can theory-craft or make up just about anything. It's just as likely to be canon-compliant. A true blessing and curse for Duskwight lore seekers. The sad thing is that, at this point, we're unlikely to ever get any concrete answers about Duskwights. They just won't get as much attention lore/narrative-wise.
