The newest downloadable PDF on the Skyships & Summons game page included the basic rules for v0.6, along with an extra "Advanced Rule Pamphlet." This "Advanced Rules Pamphlet" contains the following:

• Clarifications on how the dice-rolling rules work, along with ways for a GM to let players "fail-forward" in fun ways.
• Plot hooks for long-term campaigns using the "Skyships & Summons" system.
• A map of the continents of the fantasy world called Tellus, made using Azgaar's Fantasy Map Generator v1.71!

Hope this stuff proves to be fun!
