Pathfinder Warlocks as Templars

For people who want to have warlocks as the templars for their Athas game, Rogue Genius Games came out with a class called the Hellion which is definitely warlock inspired, has 6th level casting, a bonded object (with amulet giving an eldritch blast), and class features that are a mix of talents and hexes. It’d be easy to make a patron for each sorcerer king.
