For the record this isn't actually the final boss of the game that's still Rollo and Lila but this is the last boss of the new content questline. But does that mean everything is resolved and wrapped up in a neat little bow OF COURSE NOT! See there aren't anymore sidequests given to you but we do have something known as the sacred realms which is a dungeon that basically requires you become a speedrunner making your way through the sacred realm to find more information and picking up bits and pieces of the story as you go until you can repair a broken monument containing the final piece of Ragnar's story. I'm unsure if there's a true final boss against Canoe (or Canute I'm not sure) and Astrid or not because there isn't anything listed in Time attack but Ys 10s time attack isn't exactly something to take as Gospel on what is and isn't a boss.

Speaking of Story I'm not 100% sure what the situation is here as I haven't sat down to really translate this final part of the story but from what I can gather Ragnar and Yule were the origins of mana wielders and seemed to have a relationship possibly similar to Rollo and Lila but while our Noah's ark loving Vikings had a bittersweet conclusion to their tale this story just ended in pure tragedy. That being said I still haven't finished the sacred realm stuff so who know what there may be... lord knows I'm crazy enough to try and find out.

And one last question... who was the horny SOB at Falcom that gave her monster form massive breasts?!?

Regardless awesome fight, great music, and a much more enjoyable ultimate challenge than Vermodr was.
