About

You run research for the Forren Foundation, and the job description is simple: capture Holy Core Battlemaidens, study them, and bend them into loyal followers. There's no pretense about scientific ethics here.

The loop is capture-and-convert, pushing each maidens from resistance to obedience through whatever methods the Foundation sanctions, with turn-based encounters standing between you and the next subject. It's less about seduction than processing — bring them in, break them down, log the results.
