We're working on it. We've got a lot of the mechanics in a fairly good place, at least for what we want to do, and most of the "core" player options are present. Now we just need to take all the long bullet-lists and convert them to full English text. And also write in all the background stuff that's in my (the lead author's) head but that has never been written down anywhere. And make sure all the revisions and rule-versions are consistent. And also add more player content and options.

Well… we're working on it.

Changes since last time:

  • Significant reorganization:
    • Created sub-chapters under Items, A Tour of the Commonwealth, and *Other Nations8.
    • Moved backgrounds and languages out of A Tour and Other Nations, and put them in Backgrounds and Languages.
    • Moved the "Major X" content for each faction/province into their own sub-sub-chapters.
  • Finished updating the Example NPCs to the new layout.
    • It was pretty mechanical, so some outdated data almost certainly remains.


  • revise items-and-down for new attack skills.
  • Edit the example section to match the last like 3 revisions of changes, god.
  • Update the Ratfolk entry to flow a little more like the Elven one.
  • Lots more player options!
    • I did the classes and powers and backgrounds that where interesting to me, but I really need to do samples for others too.
    • More Items! Especially more magical items!
  • Change Maneuvers to maybe Feats as the name for martial powers.
  • Convert “walk” and “run” movement to “base” and “full”, respectively.
  • We need massive editing. I’ve been resisting, but it’s large enough that we can’t use it without some major clean-up.
  • Rework the intro sections.
  • Update the “bestiary” part, since it’s more-than-two rules revisions out of date.
    • Also, tag the things in it with a difficulty hint.
    • And add Sinestro’s Cold Shadows and Sauce’s Whisps.
  • Fill in the Raptor's Protectorate and the Shaded-Sea People, dear god.
  • Add examples for all the skills.
  • Add optional rules for ranking profession skills by wealth?
  • Copy over a bunch of the finalized names, dates and units.
  • fill in the stubs in travelling and common hazards.
  • Fill in the Secrets section.
  • Finish updating the From-the-Authors section,
    • including renaming the file.
  • Right now, the Basic Rules chapter is... fucked up and mostly asides.
    • And right now the definition of "basic proficiency" appears to be in a side-bar, which isn't ideal.
  • Write the rules for recovering raw materials; I'm thinking scrounging, "gathering professions", and breaking things down.
    • And fix the time-table for producing recipes; it's out of whack right now.
  • Added CV's banners!

Editing Notes

  • I need to go through and use the term Tag consistently. And then also re-work most entries to use Tags.
  • Likewise, use “Check” consistently, as opposed to “Test”.
  • I’m trying to use “the character” or “a character” consistently, to emphasize that players and NPCs use the same rules. I need to go back and edit this to be the case.
    • Sometimes this results in tortured language, I might need to reevaluate.
  • I’m trying to use “they” in cases where gender is unknown or unspecified. I really hate the “pick an arbitrary gender” writing style that many d20 systems use.
  • I’d like to use lower-case for race names (“orc” and “elf” instead of “Orc” and “Elf.” I was using caps for a long while tho, so much editing will be required.)
    • I give up, I'm going back to caps-ing race names.
  • It’s spelled “orc” by the way.
  • At least for now, I’ve decided on just calling it magic. I wanted to use something a little fancier, like essence, but I couldn’t come up with something I wanted to commit to. I’m using the terms mage and spell, psion and sleight, and priest and boon. I may revisit this.
    • I’ve specifically avoided using “arcane” as a description, because it annoys me that a generation of grognards are growing up who think that that word means “knowledge magic” and don’t realize that it actually just means “difficult secret.”
  • Note: I need to use Emerald Plane, Ruby Plane and Worldspine consistently.
  • We use colored highlighting! We put sidebars and clarifications in teal, FIXME notes in yellow, examples in purple, playtester questions in salmon, and GM Guidance in green.
    • There may not be enough difference between GM Guidance and most Sidebars to give them different colors.
    • Also, the two GM Guidance blocks so far are really long, so treating them like a sidebar might not work.
  • ... does anyone know of a gender-neutral replacement for words like "craftsman" and "Swordsman" that won't also result in tortured language?
  • I think I'm going to start using a "bold-at-definition, italics-at-reference" style for keywords.
    • I'll need to go back and reformat... a christing lot.
  • For now, we're using the term Movement Mode. We might change it to Movement later.
