Core Mechanic	Combat and saving throws use a d20 plus bonuses, with high results overcoming a target number or opposing roll. Skills use d100 and succeed when the result is at or below the character's percentage.	Each hero has four action dice, one for each action type (Attack, Brace, Compel, Maneuver), with the die size set from d4 to d12 by the relevant attributes. To act, roll the matching die and read it against two thresholds. Against an obstacle, the Guide sets a failure threshold and a struggle threshold. Against a foe, the target's attribute is the failure threshold and its defense is the struggle threshold. Beating the higher number is a Success, beating only the lower is a Struggle that costs something, and beating neither is a Failure. Attacks deal damage equal to the roll minus the target's Guard and Armor, so one roll settles both the hit and its severity.

Best For	Groups who want long-form science-fantasy campaigns that move from a ruined Earth to other dimensions. The game suits tables whose GM will decide which parts of the broad setting a campaign uses.	Groups settling in for a multi-session campaign who want combat built on resource trade-offs, spellcasters that each play differently, and a Guide comfortable improvising rulings. The island-hopping rescue-and-rebuild structure rewards tables that enjoy both tactical fights and settlement-scale stakes.
Highlights	Occupational and racial class packages assign distinct abilities and advancement tracks, giving each archetype a different role in the party. Mega-Damage places many supernatural creatures and war machines on a separate durability scale beyond the reach of ordinary Structural Damage Capacity attacks. Rifts and ley lines make dimensional travel a standing feature of the setting, letting campaigns move between devastated Earth and other worlds.	Each of the four defenses both resists incoming actions and doubles as the resource a hero spends to power abilities, so every turn weighs guarding against acting. A hero rolls a different die size for each of the four action types, so strengths and weaknesses live in which die they pick up rather than in numeric modifiers. Invoking an Ideal after a roll spends Spirit for an advantage die the Guide sizes to how dramatic the moment is, linking vivid roleplay to a mechanical boost.
Considerations	Character creation combines rolled attributes with extensive skill selection, making first-time preparation lengthy. Combat asks each player to track an action economy, active defenses, and which damage scale applies. Magic and psionics use separate point pools and power procedures, adding class-specific rules to the shared system.	The three spellcasting callings each run a separate resource economy, creating a real skill gap between players who take a magical calling and those who do not. The Shinarian origin locks Agility at 0, which bars the Wanderer calling and leaves those heroes unable to evade, outflank, or hide effectively. Sizing invoked Ideal dice, setting challenge thresholds, and reading the Dreamshape table all rest on Guide judgment rather than fixed numbers, which favors improvisational Guides over those who want firm procedures.
