The Kalai language was the native language of the Kalai species, mysterious beings who inhabited Zirtran's Anchor, in the Phosphura Belt Nebula. The language was difficult to translate into Galactic Basic Standard.
Their starship and residence was named in this language, but other inhabitants of the space station referred to it by the closest approximation in Basic, Destiny.
