Deraboam

Deraboam is a merchant in Dragon Age: Inquisition. He is located on the upper level of Val Royeaux.

Involvement
He 'sells' only one item, though no-one has ever actually purchased it, and he claims it is too expensive to be merely 'sold'. Instead he lives off the bribes and tributes wealthy visitors give him to try and get him to lower the price or reveal what is in the box. He also claims that the actual item is irrelevant and that it is the price that makes it valuable; the notoriety from being the one who bought it outweighs the usefulness of the item.

If you purchase the box and examine the contents, you will get the war table operation The Big One?.
