How Venat can be sundered? She's serving as Hydaelyn's heart - If Hydaelyn sundered her own heart, shouldn't she too be sundered? Are their copies of Hydaelyn on every shard? Speaking of which, how could Hydaelyn cross shards to snatch Minfilia's soul when that should be impossible? Also what's with taking Emet's soul when later he's brought to the end of the universe and presumably gets back to Etheirys no problem?

I dislike the writing around Venat to an extreme degree. It's screwed up on every level.
