Spaces of the Unknown

ZIP File

Spaces of the Unknown is a fantasy tabletop RPG, designed for play-by-post gaming on the internet.

This is a dead simple, light, fantasy role-playing game designed to be played on the internet using the most awesome human invention: the written word.

Number of players: At least 2, one GM and one or more players with characters

Setup: An online forum, shared email thread, or shared Google doc

Dice: Standard gaming dice, including d20s, d10s, d8s, d6s, and d4s. Recommended for online rolling:

RPG inspiration: Early Dungeons & Dragons and Searchers of the Unknown

The players will explore abandoned and overrun ruins, and reclaim them for civilization.

Don't need a new system? The game includes 6 lairs stocked with monsters, ready for old-school play.

What makes it different than other RPGs?

  • The GM rolls all dice during play.
  • All PCs are fighters (with some ability to cast magic)
  • Spells are typically cast by reading a spell scroll
  • There's no gold and no gold economy
  • When a PC's Hit Points are reduced to 0 or less, the PC is not killed or knocked out; he or she is sidelined. A sidelined PC is still conscious and can grant bonuses to other PCs, but cannot attack for the rest of the fight.
  • The party levels up as a group, not PCs individually.

Here's what you'll get in this release:

  • A PDF containing all the rules, with maps by Dyson Logos and art by Peter Seckler
  • An .azw3 file for newer Kindles
  • A .mobi file for older Kindles
  • An .epub file for other eReaders
  • An .odt file with all the text, so you can copy-and-paste whatever you need
  • A PDF of character creation that you can send to players (or download it here right now!)
  • A 1-page PDF "cheat sheet" of the game's core rules (or download it here right now!)
  • A 1-page PDF "cheat sheet" of the combat rules in more detail (or download it here right now!)

Confused. If it says 1d20+level must be greater or equal to the defender’s AC then why does a third level character need a 9 to hit a monster with an AC of 6? Shouldn’t it be a roll (and level) of 6 or more? If the pc rolls a 3 they add their level to make 6 and a hit no?

... and this is the obligatory "will this be available in print?" question.

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.
