Oh wow, I was actually completely unaware there was an alternate point of view.

My impression listening to the English cutscene was that Midgardsomr resented Hydayln's blessing thinking he couldn't kill me when I had, and took it away so maybe one of his kin or someone else could kill me. I never got the impression that I was being tested, just being messed with. Especially with 'Ishgard will burn'. It's intensified in the next scenes following as Moenbryda is about to die and we can't get Hydayln to listen to us 'If only he didn't take my echo!'

I hope in the next story arc Ishgard's sins are brought to the light and we see what japanese midgard was talking about
