Not at all what I expected from the Lost Guild...and yet it's really awesome. I really enjoy the unique narrative told here, and the outlook is decidedly dark.
The only issue I have is that some of the explanations feel a bit disconnected. There's a lot being told through narrative (which is awesome), but not a lot of explination of what all these things actually are. It helps build mystery, but some of the terms come at you quick and without warning. Unlike a lot of OP products, there isn't a glossary for reference to the terms. While a lot are shared with Mummy: the Curse, enough are new that it might have been a good idea.
That said, richly dark atmosphere, decidedly unique antagonists or players, and a revelation of a mystery that's been on my mind since Mummy hit. I definitely suggest it for any Mummy game.
