About Etariya: Septachroma, from BoardGameGeek:

The Septachroma Stones of Genesis Players are 2 Gods of Light & Dark, fighting over control of the mystic island of Etariya. Players take turns guiding the 7 tribes into regions of "Eternal Day" or "Eternal Night" and try to lay claim 4 tribes for themselves to control the island. This is a lightweight 2 Player Abstract Game with beautiful components and 3 variants for advanced play. The black & white areas of the island are created with transparent plastic overlays to provide a different layout in every game. -description from the publisher
