Golosian

Golosian was the language of the Golos. It sounded like crackling and rustling and was made of a series of signals framed in semiotic strings. It was significantly more complex than any human language and even the TARDIS' translation circuit was unable to translate it. It took 15 years for the translator Loozly to begin to understand it.
