help on gettin Keiran as a hero...

I believe you have to finish Keiran's scavenger hunt first.
Walk in to Hall of Monuments and walk towards Gwen. Keiran should enter eventually and start a dialouge. Let it finish, then enter Ice Cliff Chasms from EotN outpost and Keiran should be there and he asks for you to collect some things. No you don't.

I didn't do anything about the scavenger hunt and still managed to get Keiran.

I'm stuck on this part too. I consulted guildwiki to see what I could give him, and so far he has accepted 4 dwarven ales, 3 bowls of skalefin soup, 4 red bean cakes, and 6 votive candles.

But he still acts like I haven't given him anything. I don't know what else to give him because his dialogue hasn't changed and the "quest" doesn't update to tell you anything about how much you have collected or what is needed. You have to say something like "What else do you need"

And he'll say "The girl motherf%$&*#"

Then you rejoice in HoM

If you're POSITIVE you've given him everything and this option isn't availible, try finding a scene in HoM first.

Maybe I miscounted, or maybe I needed to give him 5. I'm glad it was that, and not one of the much harder-to-farm items I was missing.
