The bag is an artifact found in the wreckage of a caravan by Orem, Randus, Torq, and Smith. While at first it appears to be a mundane leather haversack, on closer inspection, it proves to be bigger on the inside. By no clear consensus, the bag falls into Orem's posession. Though the following adventures, it was used to carry almost everything the party acquired.
The bag is discovered.
