The Lost Valley is a Domain located in Fuao Vale in The Chasm. Clearing this domain gives Artifacts. Challenge domains with higher levels to get better rewards.

Unlocking the Domain

The domain can be unlocked by placing two Geo constructs at equal distances between the Unique Rock and the closest rock pillar. (It also suffices with one Geo construct on the Pressure Plate.) Afterwards, a strong attack against the Unique Rock Pillar located nearby will create a resonant quake to reveal the domain.

Unlocking the domain grants the Wonders of the World achievement "The Lost Valley."

(Approach the nearby Unique Rock Pillar)
Paimon: Huh, this big rock has a gold shine, and its color is the same as the rock pillars around it. Maybe there's a secret here?
Paimon: Wow, Paimon's never seen raw minerals this huge. There's a wooden sign beside it too. Let's go have a look.
(Activate the Unique Rock Pillar)
Paimon: Whoa, the ground's shaking!
Paimon: Look! The shockwaves are traveling between the minerals. So, this is the "resonance" between Geo Constructs, huh?

Paimon: We've done it! Now let's see what's hidden in here...
