Hey, I've checked on Grimtools map to see if I didn't miss areas or NPCs, and I found out that near to the sunbane oasis rift and sanctuary of Horran there should be a NPC called Brother Haggan. I guess it is related to Kymon's Chosen, however he is not there in game... I'm in Ultimate and Reverred with Kymon's Chosen, is there a prior quest to make him appear (I've done all vanilla quests from Kymon's Chosen)?
No idea about Brother Haggan, but he doesn't do anything anyway as far as I know.
As for Daila, have you done her quests in Homestead and Mournedale? If not, then she won't appear in Kovan City.
Also try verifying your game files, see if that helps.
No, neither Kymon's or the Order are really involved in FG, though you will see them from time to time.
