The Precursor alphabet is a substitution cipher written by Naughty Dog Inc. for use in the Jak and Daxter series. It appears to have deep Precursor origins as it is used in almost every Precursor artifact in the series, as well as common signs, posters, and other game elements. Although it is not the earliest of Precursor forms, as shown by the dark satellite in Jak 3, which displayed a cipher made entirely of lines and dashes. The following text was translated using the adjacent legend.
