Paladin was a term that referred to some kind of knight.
Paladins of the Chatos Academy were early forerunners of the Jedi Knights.
Paladins of the Knights of Zakuul were elite units who wore black armor rather than the gold of normal Zakuul Knights.
Paladins was also a name for the palace guards of Iziz; however, they obviously were unrelated to the former. A Paladin character is mentioned in the Rodian play The Trickery of Vosdia Nooma.
