Old Clubhausian is a simplifed language used during the time of the Republic of Clubhausia. It was mainly used as a code-language for sharing secrets, and largely fell out of use during the Great Ruislip War due to the fact all the leaders of the warring nations knew it, meaning messages were no more secret then if they were spoken in English.
A December 2019 survey of the Clubhausian ruins discovered that, albeit faded, under the names of the founders etched into the wall of the Clubhaus was the names in Clubhausian. After consulting the former emperor of Lorentia, a book containing all 26 translations of the english alphabet into clubhausian was found, albeit damaged. Using both, the Lyteran Government compiled a list of the translations, which is found here.
