The Bone Age


The Ape-Turtles didn't plan on three flying saucers crashing into the planet.

The Bone Age is an old-school RPG of neolithic-era tribes struggling against the sudden arrival of bug-eyed aliens. You play a Tuzanian, a tribe of jungle-dwelling, vine-swinging, pterodactyl-riding, bone-wielding savages, or a Cruach, giant-crab riding cave-dwellers living in mountains bordering the jungle. Radiation leaked from the Invaders' crashed flying saucers spreads on winds of purple, blue, and white, mutating the land and its inhabitants. Meanwhile, a race of turtle-apes and ape-turtles sleeping in stasis beneath the surface awoke...1,000,000 years later than planned. And they were not impressed by the native population – or the alien Invaders.

The Bone Age isn't based on a specific OSR system, but comparisons can be drawn to Swords & Wizardry, Labyrinth Lord, Lamentations of the Flame Princess, and Dungeon Crawl Classics. The base mechanic uses a d20 where higher rolls are better than low rolls, and works in a similar fashion to the way saving throws and attacks work in Labyrinth Lord. Thus, an ability might be expressed as 12+, meaning you want to roll a 12 or higher on a d20. Placing the target number in the hands of the players means they get the thrill of shouting "My attack hits!" or the agony of lamenting "I failed my mutation roll," as opposed to the Game Master setting a secret Difficulty Class.

The Bone Age uses a class & level system, with levels maxing out at 10. While most of game mechanics in The Bone Age will seem familiar, there are some things that stand out in contrast to many other games. The most important is the concept of Attunement. The land of The Bone Age – called Kalsentia – is itself a living entity, and the creatures that inhabit it can develop a spiritual connection to various geographic regions. These regions are represented by hexes on a map. If you are attuned to a hex, you function more effectively in it. You can attempt to attune to new regions, but you risk the wrath of the land if you offend it – rock slides, earthquakes, and floods are just some of the signs that you have angered Kalsentia.The land is brutally hot. The north is dry, the south is humid. Many regions see rain only once per solar cycle.

Some bullet points of interest:

  • With the exception of the PCs and NPCs, The Bone Age harbors no terran life forms; no horses, no dogs, no bumblebees, no bats, no platypuses.
  • The methods necessary to create metal have not been discovered.
  • The bones of ancient creatures litter the landscape. Bone is thus a resource used for a variety of tools, including weapons.
  • Three alien ships crashed on the planet one solar cycle ago. Radiation leaks from those ships continues to be carried by the wind, infecting the land and its inhabitants with horrible mutations. The aliens are collectively called the Invaders. 
  • Advanced technology has been pilfered from Invader ships and Invader dead. Wise men and women have attempted to understand the strange items, to varying degrees of success. Player-characters will discover Invader tech in various states of repair. The use of these items can be unpredictable, wondrous, and dangerous.

Just making sure I’m getting this - in the example on pg. 6, shouldn’t Azora’s MoS be +3 instead of +2 (rolled 12, +2 for AGL, for a total of 14 compared to a Stealth Ability of 11+)?

You're correct! I'll fix it in a few days, after which hopefully any other errors are brought to light. Goid catch!

There will be one. I'm writing more material for it before I do. There will be a free 'upgrade pdf' for folks who purchased the 90 page pdf version.

Cool! What will the new material consist of, primarily? I’d love to see an adventure.

An adventure and a GM 'Toolkit' of tables for things like campaign plot seeds, toxins, etc. Thanks for the enthusiasm!

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
