Cuvacian language

Members of the sentient Cuvacian species spoke a language which was difficult for other sentient species to understand. The Transliterator, a product by Consolidated Learning Systems, was capable of translating the language and this was used as an example of its capabilities in the 50th issue of Galladinium's Galactic Datalog of Fantastic Technology.

Behind the scenes
The language was first mentioned in Galladinium's Fantastic Technology, a Roleplaying game source book produced by West End Games in 1995.
