User blog comment:Nomad27/What was the Black Scripture's goal in using Downfall of Castle & Country?/@comment-11990868-20150912025740

most likely, they wanted to control ainz. Remember the Sun Scripture? and it was revealed that they were being monitored? Well, seeing one of their WCI's was 1 hit killed by a single person they prob thought that if they managed to have such a strong being under their command then they would be unstoppable. So, they sent out the Black Scripture for this task of mind controlling such a being but shalltear's 'children' ran into them and after they quickly killed off, shalltear ran towards them in a fit of rage and...you know the rest. But, this is just speculation on my part.
