For 10,000 years the D'ni people thrived underground, building a civilisation that on first examination appeared almost perfect. Thirty-four kings ruled over the empire, moving it forward, shaping it, honing it to understand and master the wonderful art of writing 'Linking Books' to unlimited 'Ages', then it died. Now, over 250 years later, it has been rediscovered.

Immerse yourself in a story of discovery. Follow Yeesha, eccentric daughter of Alrus, encountering linking books, and solving puzzles as you adventure through surreal worlds beyond your imagination, unlocking the key to the mysterious, lost D'ni civilisation.
