Potato has a point. Especially if it's evil. They would send demonic entities of all types to try and stop the purifier from ever moving forward. I would say two body guards would not be enough. the least would be 4-5 for story reasons. I mean (for exaggeration) what if the enemy DID send their best in the beginning? It would be over before they could start. So 3-5 individuals who are powerful.
