The holy book of the Menaphite Pantheon, the Book of Light and Day, is traditionally written in the Menaphite language. According to Reldo, the librarian of Varrock Palace, the High Priest of Icthlarin recently sent him an excerpt of the text depicting Tumeken's Dream, which was written in "Menaphosian." It is probable that this is related to, if not synonymous with, the greater Menaphite language.
