A meteor strike in the taboo crater country opens up a huge chasm in which lies a largely intact city of the Ancient Ones. The resulting land rush to go claim the newly available cache of ancient artifacts draws interested parties from all over Terra A.D., and at the direction of your tribal elders, that includes you and your Seeker team.
A solid enough adventure but not one I'd want to draw out over multiple sessions without some major tweaking. It just feels a bit generic (even for MCC) in its approach. That being said, it utilizes the artifact skill check quite a bit and there are a few technological wonders for the characters to fiddle and have fun with. It also contains a fair amount of opportunities to add random mutations to the PCs. Overall, not a bad module, just one I'd spice up a bit. The villain feels anti-climatic but there's a good opportunity to really bring out the competing tribes element. I'd maybe take that to the next level instead.
