I'm working on the following miscellaneous quest:
Take Torygg's War Horn to the Shrine of Talos for Elisif the Fair
I have arrived at the destination, but I cannot figure out how to get the war horn out of my inventory and leave it at the shrine.
Activating the Shrine of Talos gives me Talos' Blessing, but doesn't leave the horn. I cannot seem interact with the great statue of Talos in any way. Since it is a quest item, I cannot drop the horn on the altar or on the ground in front of it, and for the same reason I cannot leave the horn in the satchel on the altar.
How do I leave Torygg's War Horn at the Shrine of Talos?
