Taniwha has to move the skeleton to get to the multiple items in the chest, which turn out to be several books and scrolls. The three books are bound in black leather and blank; they could probably go for 25 gp each.
The rest of the items are scrolls: three of them are clearly magic by the way the letters squirm and shift under Taniwha's gaze, unreadable; one is the deed to the house; one is the deed to a windmill; and the last is a signed will bequeathing everything in this chest and all other family property to Rosavalda and Thornboldt Durst in the event of their parents' deaths.
After all this, Taniwha notices a final scroll clutched in the bony hand of the corpse. This one is bears a shiny red seal, but it's not the Dursts'. Instead, this crest depicts a raven in flight before a cameo of a gloomy castle in the distance.
