Originating from Asia, this group of tongues is the second most spoken by Human and Human-derived populations since the birth of Sol Common - and was a primary contender to be the Sol Federation's official language. Many loanwords, idioms, and cultural relics of Japanese, Ryukyuan, Korean, and other societies have managed to persist within it, especially in the daily lives of speakers coming from Martian cities."
