Although he did play a major role in the God Wars and brought several races, including orcs and goblins, to Gielinor to the world to be in his army, we do not see him in-game. He was banished by Guthix from the world along with all but one of the gods, but the descendants of his original army still live and still worship him. Players do interact with his armies during various quests and we even encounter the ‘Chosen Commander’ who is an ancient Bandosian legendary commander. However, aside from this, we do not encounter Bandos or any of the other lost gods in the game.
