Those Who Wander
Core RulebookBest For
Groups familiar with d20 fantasy who want deeper character customization, inclusive design covering any parentage pairing and accessibility for disabled characters, and long campaigns where each hero's 20-step path diverges from the rest of the party.
Core Mechanic
Roll d20 + ability bonus + proficiency bonus against a Difficulty Score. Abilities use direct modifiers (−1 to +5) instead of base scores, removing a calculation step from every roll. Character progression replaces classes and levels with a 20-step path: at each step you choose between two or more diverging features, and prerequisites gate later options.
The d20 core uses direct modifiers against a difficulty, skipping base ability scores. Its distinctive systems are Step advancement and Heirloom progression, which grow characters and signature items in parallel. Spellcasting and a health pool fill out the build.

Highlights
Parentage system inherits traits from any two birth parents across 15 peoples (dwarven, elven, human, halfling, avian, celestial, draconic, genie, gnoll, gnomish, goblin, kobold, infernal, orc, plus Complex Parentage) for hundreds of pairing combinations. Accessibility rules treat Blind and Deaf characters as mechanically viable heroes and integrate prosthetics and wheelchairs as part of the character. The 20-step branching progression replaces classes and levels: each step is a choice between two or more features that gate further specializations. Awakening heirlooms (weapons, armor, trinkets) gain new properties as characters take steps, growing in power and personality alongside their owner.
Considerations
477-page rulebook with substantial mechanical innovation in character creation requires significant reading before a first session. No adventures are included in the core rules: GMs must design their own scenarios or source from d20-compatible content. The steps system departs from familiar level/class structure, so players coming from d20 fantasy must learn a new progression model. No native rolled initiative: the storyteller chooses one of four ability-based turn-order methods at the start of each combat.
