Dagas is one of my favourite blades in Xenoblade Chronicles 2, maybe my favourite original one. His design is so cool and demonstrates the eloquence of his supposed monarch self of the past. His voice acting is really badass too and displays his magnificence.
I love the idea of him being the ruler of a past land. Whether it's a delusion of his or reality, it's interesting to think about a past nation which a blade ruled over. You can imagine it with how Dagas is as a character. Though it brings into question who his driver may have been at the time.
Regideria being a destroyed kingdom is also an interesting plot point. We know Torna was destroyed 500 years ago during the Aegis war so Dagas could've ruled over the kingdom back when he was summoned in that era. I do like the development he has across his quest despite that.
Overall, he's a cool blade who also has an interesting concept around his backstory. I always wish some of the blade quests went more into the world building of the game rather than just the blade itself. This is a big reason Dagas' quest is so interesting to me personally.
