From Tsunami Wiki
The Bard says: Once long ago a race known as the D'ni existed. They burrowed deeply into the rock of their home world and chose to exist within the massive caverns they carved from the very bones of the world. Their accomplishments were vast but all paled in comparison with their ability to write. They did not write ordinary books. Using special ink, paper, and a language crafted over a millennia they forged links to different worlds and even times. The D'ni empire comprised over a thousand worlds which they called 'ages'. Alas the D'ni capital city was destroyed and the links closed forever, the citizens of the great civilization scattered throughout the worlds they linked too. The son of one of these refugees was called Atrus'. His grandmother and father passed on the knowledge of D'ni writing to the young man and he become quite a talented writer. Many years ago he linked to the land of Tsunami with his wife, but after witnessing the struggle of the various holy factions and the viciousness and greed of its inhabitants, he chose not to reveal himself, or any knowledge of the D'ni civilization. knowing full well if the knowledge of the linking books fell into the wrong hands their holy war and violent ways would spill into countless other ages. Loath to destroy any link, he entrusted the linking book to the Great Library on the Tsunami Mainland, knowing that within the vast store of books and tomes it would remain safe. Anyone visiting Myst should be wary for though any may travel to the island, none return without the help of Atrus, if at all.
