Honestly.. I teared up a bit too. It was so sad. And was it just me or did General Gaius look genuinely sad to see that his friend was really gone. I mean, yeah the guy was evil, but I kind of felt bad for him that what was left of his best friend was the one who killed him.
I might have heard the cut scene wrong, but I think that moonblood guy said there were five blades. And there were five light sources on Ahrah that were blinking out as Dust died which might be what those stood for. Look at 2:46 in the video above. I want a sequel for this game. There is so much more they could do. Maybe one of those Elysian blades is evil as a counter balance to Ahrah. Perhaps in a sequel Dust will find someone as powerful as himself wielding one of the blades. It could be a Jedi vs Sith kind of plot line. Also.. Fidget is a Nimbat.. and her tribe has been the guardians of the sword for what.. centuries I think. Even tho we saw normal villages, Mudpot people and Moonbloods, we never got to see where Fidget came from. Maybe in a sequel we could see the nimbat village and possibly a new continent of creatures and characters. Perhaps since Dust turned into a dust form at the end of the game and flew off.. perhaps he was being carried away to where he needs to be next to fulfill his destiny.
