I suggest adding a few more tidbits of information to help roleplayers researching lore in the game:

Names Matis names are much like latin names. With personal names like Liccio, Sergio, Lini, and Chiaro one might think they were in the Mediterranean rather than a world-sized tree. Family names also ring with a latin flavor; Chialdo, Chiacco, Antori, Lildo, and Sinia are a few examples.
