I dismissed Teldryn right before I went into Hrothmund's Barrow, and now I can't find him anywhere. He is not back at the Retching Netch. He is not at Hrothmund's Barrow. So where is he?

Any help appreciated.

Did you make him a steward perhaps? Also remember it could be up to 3 days before he returns to his loading cell.

Wait outside The Retching Netch for a week. That worked for me and Faendal.

I thought you were going to say he was Dead...
Id give him the best armor you can, I gave him blackguard, He wanted to keep his Chitin Helmet tho...

Im pretty sure you cannot make him a steward. Where did you get this from? Or, are you just throwing out stuff without thought?

Followers have to walk back to their "home" location. It can take quite a few days.

Patience i quess he will come back sooner or later
