The fourth level of hell is Phlegethon, and those sent here committed crimes against Sol Deus of a greater nature than those found in Archeron, for here can be found those who more actively sought to lead the faithful astray. Heretics, who lead those away from the light of Sol Deus can be found here, existing in total darkness while they stumble around in fields of piercing thorns. Here too are the Fraudulent, built into the walls of a cell like bricks, forever wailing for mercy. Thieves too can be found here, locked in a massive cell whose walls are composed of the fraudulent, with a single golden key amongst them. Forever do they covet ownership of the key, and forever do they steal the key from each other before any of them can unlock the door. Joining these sinners are the Blasphemers and the Alchemists. Both of which falsify either the spirit or material of things, and both of which are covered in leprous lesions and scabs, which they unsuccessfully pick at to remove.
