Now I remember why I probably stopped playing Fire Emblem Heroes. It's because I hate their original story mode. It was fine up until book 7. Book Six was tolerable, I think. I barely remember it, but I don't think it was ever that bad. Books 1 to 5 were all really good, although book 4 was a bit underwhelming. And Book Seven's time travel plotline was horrible. Just horrible. I actually remember looking for negative feedback to make myself feel less alone, only for me to get lost on a negative rabbit hole that destroyed my mood.

For those who think Hríd is the eldest Nifl sibling, Fjorm confirms the order in Book 2. I always remembered that Gúnnthra was the eldest, and finally found where it was mentioned.
