Geothermal Valley - The Architect's Crypt (Part 2)

Use your axe to break down the crumbling wall.

On the other side, drop into a subterranean pool.

Pick the mushrooms growing on the ledge on the left, and then dive beneath the surface to find a hidden tunnel.

Swim through into the next part of the cave.

Follow the tunnel to the next drop-off. Before climbing down, look to the left for a document (12/33). It is titled Rivkah, the Architect and belongs to the Crypts of the Founders series (Greek).

Ignore the cavern off to the left for now. Drop down on the right and continue northeast...

...to find a mural (2/4), also in Greek. It is Rivkah, The Architect, from the Crypt Murals series.

Continue around the next bend. Then use the zip line to slide across the cavern into the elevated tunnel that leads to the crypt.

Open the sarcophagus to get an ANCIENT BOW PART (3/4), plus XP and 3,000 Expedition Credits.
