[Brinniel]

We could create an item similar to the Nauglamir (perhaps a crown, staff, etc), made around the same time, but it was lost and forgotten until 50 years ago. We would also need a name for the item (don't ask me; I haven't a clue what it should be).

I was thinking of wargs, goblins, and trolls as our enemies rather than dwarves. The dwarves have no clue that this expedition ever happened, as the elves kept the expedition secret to prevent any future wars with them.
