I've finished all of my quests in Ravenscar, and am currently just starting out in Hrundle Fjord, but before I continue on there, I was wondering how exactly I would get to Helgrind Warren? I still have the Helgrind Warren yardbird left, but I never remember going there. I read somewhere else that I have to get Jontun's quest but I can't figure out how to find that either and there's nothing anywhere telling me how to get it. If you can help, then thanks.
Go to the big blue palace under the bridge, where you fought Jotun.
Helgrind warren is a side dungeon, I think the one on the left. Inside, you must fight some Balance colossus types and defeating them will open up a set of doors. The yardbird is hidden inside the Storm room, off to the left on a rock. You don't have to fight the storm boss in there, just slip inside to grab the yardbird.
