The Cosmosdex hosts a fictional space themed encyclopedia by the same name that contains pages upon pages of lore, aliens, planets, and just about anything you could ever want to know about this expansive universe. It also hosts the webcomic [Fortuna], a fourth wall breaking comic that remembers your name, and the choices you make.
While the Cosmosdex and [Fortuna] are closely related, both of them are self contained products that are enjoyable on their own. If you're looking to start reading entries head to the Cosmosdex. If you're looking to read an adventure check out [Fortuna].
