After killing the hostile version of Cohlien Frostweaver, he drops which starts this quest. You must locate Cohlien's lockbox and use the cap in front of it. The lockbox will highlight as you mouse over it, but is unusable itself. After using the cap in front of the lockbox, return to Custodian Dieworth for your reward.

Cut scene upon putting the hat in the footlocker Edit
- the ghost of Cohlien Frostweaver appears
- Cohlien Frostweaver says: Phew! There's my lucky hat. I've been looking for it everywhere.
<The custodian smiles at the mention of Cohlien's name.>
You're absolutely right about the hat. He wore it all the time and wouldn't let it out of his sight.

I'm going to miss little Cohlien. He had quite a way with the elven women.
