The Kyrian story is… difficult to grasp to say the least.
I’m assuming it’s because the Kyrian’s main job is to ferry souls to the afterlife, whatever happens to them after that is not of their concern or within their power to control. They are pretty much bound by code of the Archon’s making, and any deviation from that puts a target on their back.
While this had the potential to be a very interesting story of moral vs duty, Blizz (as usual) went with ‘OKAY THEY R EVIL THO’ even though the Kyrian finding out that the cycle was broken had plenty of reasons to be raising their eyebrows at the Archon and their ‘duty’. Not to mention if they didn’t fulfil this purpose, the mortal realms would probably be overrun by wayward souls.
I would love some sort of follow-up though, I really hope Ben gets his deserved afterlife.
