Ancallon itself is not a language, but a concontinent which was created by Aran Kuntze in 1990.
The continent itself holds several languages, however, which include New Ancallún, Ancallún, Andarkin, Draccan, West Ancallún, Banrok, Konamoata (aka. Maratian), Dolmany, and the Language of the North.
Only short descriptions of each language survives (and a few words of one of them, but which one is uncertain).
