002 S of the Chamber of Records: There is a circular room with many platforms. Two collectibles are at the top of the chamber. There is one Document on the northern end, where you leave. After getting it, search the eastern exit, and pick up a Coin Cache.
003 N of the Chamber of Records: Examine a Mural close to base camp.
004 N of the Chamber of Records: Before going in the room with the altar, look for a small side passage with a Document on a pedestal.

006 NE of the Chamber of Records: A Coin Cache is in the massive, Atlas room at the eastern end of the map. From the altar area, look a tiny bit northwest before searching. That same room has a Document as well; it’s on the very northern tip of the room. This treasure is hard to actually retrieve. Start from the initial ledge in the room and look toward the north. There are two hanging chandeliers. Grapple between them and over to a stone ledge above the main floor. That’s where you find the item.
