Bilgeron Cogsworth of the exploration team L.O.S.T. is searching for the Drednever Expedition Team who sent out several distress signals from all over the Kingdom of Sky. The problem is they can't be found, so you must follow clues to find them. The first is a gnomish mechanical cog dropped from a droag. Slay more droags to see if you can find more cogs. Any droags in Tenebrous Tangle will do.
