The language of the sentient Mairan species from the planet Maires consisted of melodious, music-resembling tones produced by a shell flute. In the year 23 ABY, Tenel Ka, the Hapan-Dathomiri princess, employed the translator droid M-TD to communicate with a Mairan ambassador who was expressing himself in his inherent language via a shell flute.
The Mairan language was initially featured in Young Jedi Knights: Lightsabers, a book for young readers released in 1998 and authored by Kevin J. Anderson along with Rebecca Moesta.
