First things first - I return the Horn to the Greybeards, completing my task. They teach me the final word of the force shout - DAH, or "push." They have yet one more test, to see if I really, really am the Dragonborn - they subject me to the full power of their Voice, the lot of them. It put me off-balance, but apparently it was enough to tear a normal person apart. So I really am what they say I am.
A little while ago I didn't think I was ready to take on another hagraven, but with the experience I have now (like knowing all about the Shouts and stuff) I am ready to take them on and get that dagger to heal the Gildergreen tree in Whiterun. They are hidden up near Helgen - I still don't like that place - so it's quick enough to get there. The hagraven had a coven of witches at her command, but they weren't a match for my skill. And this time, the hagraven wasn't about to kill me (though there was only one).
It's not too inviting when I get there.
We are met by a couple of pilgrims, Sond and Astra, who tell us that the way to Eldergleam itself is blocked - actively, by the tree's roots. However, a few swipes in the air with Nettlebane solves that nicely - the tree looks like it's actually afraid of the blade.
Maurice is none too happy with my plan to cut the tree to get its sap - I guess he wasn't listening to the priestess. He thinks he has a better way; nothing to lose by doing something else, and I guess it would be better to not harm a sacred being. What does he do?
Now I head to Kynesgrove to meet Delphine.
