Chroma'Agana is a place in the computer game Myst. It was the second home of Atrus and Catherine. They moved here after the events of the games Myst and Riven. It was their base of operations during the restoration of D'ni, but was abandoned some time before the events of Myst III: Exile, possibly at Yeesha's birth, when they moved to Tomahna.
Chroma'Agana somewhat resembled Myst Island. It is described as having a "rocky spine" apparently running its length, interconnected buildings housing workshops and laboratories as well as a library, and features referred to as "the Eye Pool", "the Anchor Rock", and "the cliff path". Plant life includes grass and "Oreadoran oaks".
