|The following is based on Clark's Law and contradicts canon sources.|
The Tuchanq do not sleep, or at least they do not dream. Whereas most sentients use dreams to organize their memories, the Tuchanq instead use "Songs". The Song of Being contains the individual's personality, while the Song of Journey contains their memories. These must be constantly sung, and if a Tuchanq is somehow rendered unconscious, they forget the Songs and become incredibly violent.
Little is known about Tuchanq ancient history, but between 2242 and 2259, the Tuchanq homeworld was under a brutal occupation by the Narn Regime. The Narn cared little for the Tuchanq, and the occupation almost completely destroyed the environment and laid waste to Tuchanq cultural heritage.
- Song of Being - The individual's Song describing their personality.
- Song of Journey - The individual's Song describing their personal history.
- Song of Freedom - A Song describing the events of Tuchanq's liberation from the Narn Regime.
- Song of the Land - A Song about the geography and pre-occupation history of the Tuchanq homeworld.
