User blog comment:Nomad27/What was the Black Scripture's goal in using Downfall of Castle & Country?/@comment-11990868-20150912025740/@comment-26314029-20150912060022

yea it was the LN. and they didnt know that ainz did it since he was blocking their observation magic. since there had been a prophecy of some sort saying that the dragon lord would revive soon,they assumed it was him so they sent the black scripture along with the WCI (never mentioned a miko) to subjugate it. its important to note that they had no idea that a magic caster was the cause or about ainz in general.
