I have nothing - NOTHING - negative to say about this module! It wins from the very first sentence and just keeps getting better!
I won't bring up any spoilers, but long story short, the adventurers are - finally - sent off to Forgehold in The Cogs to locate the creation forge and eventually decide what to do with it.
Along the way, a plethora of (potentially) funny NPCs will cross the PCs way - there's an army of utility warforged that you as a DM can use for literally anything - and there's even a tiny easter egg hidden in one of the fitter/riggers room (LOVED it and even got a few 'arrrrws' from the players - THIS is why I play, THIS is why I DM).
The overall composition leaves for a bit of running around so use those random encounter tables!
Overall story, execution, map and everything is top notch! Once again an A-class module from MT Black and everything we could possibly want from a campaign finale!
[5 of 5 Stars!]
