"There's arguments for Pax and English and Davlian and Quenya. Not all humans in Materia speak Pax, not even a majority, although that's most of what we'll get if we start with my parents and go by word of mouth. English makes us an easier refuge for genetic engineers and other people who want to leave the Federation, which interests T'Mir. Davlian because by the numbers they're the most populous founding members of the Elendil. Quenya because we're sort of modeling it off Valinor Only Better."
