 Like many Uplift Universe species, the Tandu worship the Progenitors (a semi-mythical race that lived two billion years ago and created (uplifted) the first intelligent species) and would by human standards be considered religious zealots.They are a highly xenophobic species, viewing all other intelligent lifeforms simply as enemies or tools for them to use.They follow the "Inheritor" sect of the cult of the Progenitors, believing that upon the return of the Progenitors (an event roughly equivalent to the Christian Rapture in many Galactic mythologies) the current power structure of galactic civilization will be destroyed and the universe will be cleansed of "unworthy" races.
