Wow. The art and layout by themselves are really good, but the content (48 pages of it!) is amazing.

Go to the sample PDF on the product page, start reading the adventure on page 5 and keep reading through page 6. That is badass and an amazing way to start an adventure. I would be so excited as a player to be experiencing that story, and so excited as a GM to be the storyteller. The initial encounter goes on to quickly make your characters fully entangled with the NPCs present. This is not your typical run-in-kill-everything-leave-cleanly-with-loot. And that's just the first encounter.

I would definitely recommend picking up this supplement for Numenera.

A great product for any Numenera GM!

Contains loads of well thought out story and lore, with a great layout and an excellent flow.

Manages to capture the "Numenera" weirdness feel of the world perfectly too!

If you're in a hurry and need some content on the fly, look no futher!

The flexibility you get from this supplement is staggering. The setting is weird and interesting, the adventure is flexible, and the creatures are inventive. There is enough material here to continue to bring your characters to the world below even after the main adventure has been completed. It is a worthy addition into the ranks of other stellar third party materials.

There are enough good ideas in this adventure to fill multiple sourcebooks.

The opening can easily be placed anywhere in any world. The Iron Wind turns a cliff face into flesh and the adventurers step through it’s open mouth in search of two kidnapped children. What they find is a lost underground world reminiscent of classic D&D’s Hollow Earth. Except this world is ruled by dreaming mummies in ancient floating sarcophagi and half the peasants are mind-controlled blood sucking plants. Diplomacy and rebellion follow.

The adventure is cinematic, well paced, and the focus is properly centered on the PC’s. It’s written to engage the players, require them to make hard choices, step into the spotlight, and shine. It’s a player’s adventure. It’s written for them. It’s not like some adventures that describe an amazing scenario or a complex back-story and then put the characters there to interact with it. In this adventure, every scene is written to either force the characters to make a hard choice with real consequences or allow the players to do something awesome.

Production wise, I was really impressed. The book is very well edited and the original artwork in fantastic. My only complaint is that there could be more maps and I would have liked a more detailed description of Urbamorr, the underground city where most of the adventure takes place.

Overall though, this is a very impressive first release by a company I plan to start following closely.

There's a lot to like in this adventure. The story fits perfectly into the Ninth World setting with ancient civilizations and technologies that are fun and often just plain weird. Early story hooks lead to more complicated political struggles with factions within factions and the ending might just leave a civilization changed forever.

From a GM perspective this adventure also works well. It can be a longish stand-alone adventure spanning several sessions, and hooks are also provided for fitting it into a longer campaign. The adventure can scale for characters of any tier, and it works well for any kind of character, whether your players like to tinker, schmooze, or fight their way out of problems. There are some small rule tweaks that make running the game easier, and there's a fun montage game-within-a-game that comes up when the characters are escaping from prison.

Definitely highly recommended.

The Sun Below impresses me with its story-telling. You're going to meet creatures that are much more than what they seem. And beings that are weirder than you're comfortable with. You're going to dive into an ancient world, you'll find yourself in the midst of a struggle for power and freedom. Will you take sides? Are you going to trust a little girl? Your players' characters will have to make a lot of decisions without knowing the consequences, which is a lot of fun.
... Additional rules speed fight scenes up and make it easier for the GM to keep track of their NPC's, which is really nice. ... I very much enjoyed playing this adventure.

Let me start off by saying that I'm not a huge Numenera fan. My gaming group selected it and so I played it. Whatever my grips with the actual system is, they took a big back seat to the fantastic time I had playing The Sun Below: City on the Edge. It is quirky, epic, deep (literally), and includes some custom game mechanics in a few spots that... well, I won't spoil anything, but they made for some laugh out loud memories!

If you are a Numenera GM and has a player that, like me, isn't totally "all-in" with Numenera as a system, then I doubly recommend this adventure as a good way to introduce the 9th World.

If your group does love Numenera, then this is also an easy recommendation. The rest of my group loved it as much as I did, if not more so.
