Technically the Grey Paladins were still part of the Jedi order. With the Jedi order being so large at the time of their fall the Grey Paladins operated within the Jedi Temple as well as spread through the Galaxy. They were just seen as extremists by most "normal" Jedi, but would've still been hunted down along side the other Jedi to near extinction and could have even served as generals during the Clone Wars.

Also, I'm surprised with making a Grey Paladin that relies mainly on Lightsabers without any other conventional weapons as was their belief.
