Grab It Right
The physical copy of this adventure clocks in at thirty six pages but the pdf clocks in at about 86 and this adventure is compatible with most of the major retroclones including Labyrinth Lord and OSRIC.
This is a case where having a pdf on hand could help with maps of this location driven adventure. Ramsey Dow did the interior cartography and it matches the location's moody and foreboding atmosphere of this adventure.
The basic plot hook from Drivethrurpg goes something like this :
The secrets of the Dwarven stronghold does jump out at the party and instead the plot of the place builds upon itself encounter by encounter. There are plenty of riches and dangers to be had within this adventure for levels 3-5.
This is an adventure that is driven by and suited to the mythic and legendary but with lots of touches of ancient dread in between the pages. This adventure could be worked into a mini campaign and there's plenty of ideas within the pages where this location and its dangerous could be expanded upon.
There's lots of subtly with this adventure and plenty to keep PC's occupied between the pages in this adventure. The encounters are well thought out and balanced for a party while still being pretty damn nasty.
I liked the fact that this adventure is suitable for any number of retroclones systems and it's own take on the traditional OD&D Dwarven trope holds the plot together so well. Plenty of the ideas here are downright interesting and could make PC's never quite see any Dwarf in their campaign setting that this adventure is run in the same again.
And this is both the boon and bane of this adventure. DM will have to ask themselves what the preconceived notions about their own Dwarven races. Personally, I like where the author took this adventure. Plenty of treasure in this adventure but even more atmosphere, danger, dreadful creeping horror in this one if the DM runs it right.
Wait till this one goes on sale and then grab it, run it, and let a secret of the Dwarfs finally see the light of day if the adventurers survive this one.
