I know this idea has been done before but I figure people are still into it. It's definitely a WIP plot but the basic idea is that demigods are being kidnapped and monsters that should not have reformed yet are returning long before their due date. This is all the work of a cult made up of people who worship Tartarus. They are kidnapping the demigods and sacrificing them to Tartarus so that the monsters are reforming faster. Anyone interested? Ideas are most certainly welcome.
