As I haven't heard a reply from anyone as to whether anyone will accompany Kell or choose to stay on night watch (or a follow through on the inn spy and old man with detector for that matter) I'll post actions depending on how far things get in the post.

 

   Arawn will remain on nightwatch for the time being but if Shu's spell casting is done for the evening and Kell hasn't set out on his expedition to the warehouse yet then Arawn will accompany him, wearing a dark set of clothes hidden under a robe and remove the outer robe and roll it up and in a bag in a private and dark place when no is watching. He'll carry a face wrap as well but won't put it on until just before entering the warehouse (again in private and under cover of darkness). He'll keep an eye out for anyone following or watching as they journey back and forth from the warehouse as well.

   He'll also suggest to any still awake to please keep an eye out for anything unusual until he and Kell return. Upon a safe return Arawn will then return to night watch.

 

   If Kell has someone accompanying him or wishes to do this alone Arawn will stay at the inn and serve as nightwatch. If you've already played this through with Kell then feel free to ignore Arawn accompanying Kell if it would complicate things for you. Still, Arawn will give Kell about an hour to explore the warehouse and the time travelling carefully there and back. If Kell is alone and late more than 30 minutes beyond the search and travel time Arawn will alert any party still awake that he's going to check on him and then proceed to go on a late-night stroll, in dark clothes, near the warehouse to make sure that Kell is alright.

   Also, for Arawn's late night watch, if it happens, he'll do so without light, to give him cover and lure in potential trouble-makers.
