Core Mechanic	Roll d100 and try to land equal to or under your skill (or aptitude × 3 for unskilled checks), adjusted by difficulty modifiers in ±10 increments. The 33/66 rule grades each roll on a single throw: a success of 33 or higher is a superior success, a failure of 66 or lower is a superior failure, and doubles (00, 11, 22, …) are criticals. Four pools, Insight (mental), Moxie (social), Vigor (physical), and Flex (wild card), spend to add +20 to target numbers, flip-flop a roll's digits, upgrade a success, ignore wounds or trauma, or introduce narrative elements like NPCs and environmental details.	Build a d10 pool from an Attribute plus an Ability and count each die that meets or exceeds the difficulty, usually 6. Each rolled 1 cancels a success, and a roll with no successes and at least one 1 botches. Magick uses Arete instead: the highest Sphere plus coincidence or vulgarity and witnesses establishes the base difficulty, with situational modifiers applied afterward. Successes determine the Effect, and vulgar casting risks Paradox.

Best For	Groups who want hard transhumanist sci-fi with cosmic horror undertones, dense subsystems for hacking and body-swapping, and the Firewall conspiracy framework where cortical-stack backups turn death into a setback rather than the end of a character.	Groups who want long-form modern occult campaigns about reality-shaping power, ideological conflict, and the consequences of imposing belief on the world.
Highlights	The ego/morph split separates mind from body: characters back up their cortical stacks and can resleeve into biological morphs, robotic synthmorphs, or digital infomorphs between sessions, making body choice a tactical decision and death a recoverable setback. The 33/66 rule grades each percentile roll on a continuous scale of superior success or superior failure without rerolls, so a single throw produces a degree of outcome rather than just pass/fail. Seven distinct reputation networks (@-rep, c-rep, f-rep, g-rep, i-rep, r-rep, x-rep) replace cash for many transactions in post-scarcity territory, modeling factional standing as a parallel economy with its own favor limits and weekly refresh caps.	Nine Spheres combine to build open-ended Effects, allowing the same capability to emerge through different paradigms, practices, and instruments. Coincidental and vulgar classifications make subtlety a tactical choice because conspicuous magick raises difficulty and accumulates Paradox. Focus ties belief to procedure, so a mage's worldview determines the tools and rituals used to alter reality.
Considerations	Bookkeeping splits across an ego sheet (mind, skills, traits, pools, rep) and a separate morph sheet (body, ware, Durability, derived combat stats), and resleeving mid-campaign swaps out the morph half including pool maximums. The book takes an overtly political stance: the introduction states it is "not the game for you" if you support authoritarianism, and faction writeups present anarchist and autonomist values as the authorial baseline rather than one option among many. Routine cortical-stack backups make character death recoverable by design, so traditional life-or-death stakes need to be reframed around backup destruction, exsurgent infection, or memory lack to carry weight.	Improvised Effects place frequent adjudication on the Storyteller, who must apply Sphere permissions, focus, required successes, and consequences consistently. Vulgar magick generates Paradox even on success, so overt power can punish a mage through injury or metaphysical breakdown. Faction choices can make a cabal internally hostile, so character concepts need shared motives before play.
