Spoilers for the the second mission in Guardians of the Abyss: The Night's Usurper, Agenda 1a
If you've already made your way through The Eldritch Gate before you advance Agenda 1a... do the Brotherhood Enemies still spawn? Playing now, we resolved Act 2a the end of one round, placed the 6th Doom on the start of the next mythos phase, which means the Brotherhood goons and Xzharah spawned at A Dream Betwixt and we got worked.
I figure there's no way they don't spawn and the odds of that happening are pretty bad... but I thought I'd ask anyway! We're playing GotA standalone and have gotten pretty lucky so far, so... that draw felt bad but I suppose we were due. š
