The Malij language
is the de jure trading language of Lijatac, spread by diplomatic contact and the former Malij colonies. Ultimately it is a descendant of Original Kolij, by way of the Lij language, a heritage it shares with Chenug and Tumino.
Uset, the language of Tesyvil, appears to be completely unrelated to any other known language - it seems to have been created as a unit sometime after their departure from Keranis.
The language of the unknown continent embodies a third (or fourth, after the Keranis language family) linguistic tradition, and is different by far from any of the others.
