Not going to give exact details because I don't want to ruin anything for anybody, but I killed the dragon priest Krosis, and I'm an archer so I always have his mask on.

Certain dragons keep saying Krosis in the middle of their sentences, is Krosis just another word, or are they referring to me as Krosis because of the mask?

If the latter then that is pretty damn cool Radiant Story does work.

No they say Krosis regardless.

It has a actuall meaning which I'm sure someone else here will be able to tell you. (I have no idea myself.)

I think the dragon priest names mean something like fire or frost etc. So I think the dragon just saying something like "Taste my fire breath". or something I dunno.

damn, yea I just started to think the same when I read the subtitles and K in Krosis wasn't capitalized

far as I can see, all radiant story is, is the ability to complete certain quests multiple times. That's it.
