Disclaimer 1: most of these conlangs have been crafted to fit in fantasy environments and play with certain concepts - they're not meant to be 100% realistic or completely simulate plausible linguistic influences like real-life languages.
Disclaimer 2: these are not the lingua francas of the IOS, which are still the more traditional RL ones such as Japanese, Latin, English or Classical Chinese; and not all of these are associated with its setting ・ In red, those that share the IOS' main setting; in turquoise, those only vaguely related to the aforementioned setting; in green, those for Jambus, the world of Zyrik.
