There is only war — and the paperwork that follows it.
Everything the corebook defines, as data a Gamemaster can actually read: the rules, the wargear, the bestiary, the psychic disciplines, and the character-creation machinery that ties them together. No setting, no campaign, no metaplot — bring your own, or clone this and build one. This is a full implementation of Wrath & Glory: dice pools of d6s where 6s are icons and 4s and 5s are half of one, a shared pool of Glory the party spends and a pool of Ruin the GM spends back, and a Wrath Die that turns a good roll into a complication and a bad one into a wound you keep. Characters are built from a Species, an Archetype, a Faction and a Background, wear armour that actually subtracts, and carry the corebook's weapons at their realistic ranges in metres. Everything the rules touch exists as data. Conditions, Corruption, Traumatic Injuries, Perils of the Warp, the d66 Critical Hit table, every named combat action — all of it is a record the GM reads mid-scene and the character sheet computes from. Nothing important lives only in a paragraph someone hoped would be remembered.
This is meant to be forked. It implements the Wrath & Glory core rulebook as faithfully as the data model allows, and stops there — no campaign, no metaplot, no house style baked into the mechanics. What you get is the chassis: 23 file types, the full corebook libraries, and a Builder's Manual that explains the intent behind each schema so you can add the Tau, the Necrons, your own Chapter, or a regiment the book never printed without fighting the system that is already there.
The corebook's optional rules are modelled explicitly rather than assumed. Each one is a House Rule record with a status — Active, Not Used, or GM Discretion — so a group can see at a glance which variants this table is running. Two are on by default: realistic weapon ranges, and consistent XP awards. The rest are off, and turning one on is a one-field edit, not an argument.
Void combat is deliberately out of scope. Vehicles are modelled lightly, without inventing a damage economy the corebook does not print.
Warhammer 40,000: Wrath & Glory is published by Cubicle 7 Entertainment; Warhammer 40,000 and all associated marks are © Games Workshop Ltd. This project is an unofficial, non-commercial implementation built to be played at a table that already owns the book.
It reproduces a substantial amount of the corebook's mechanical content — wargear profiles, stat blocks, talents, psychic powers and tables — because a Gamemaster agent cannot adjudicate rules it cannot read. It reproduces none of the artwork and little of the prose, and it is not a substitute for the rulebook: it omits the setting writing, the examples, the fiction and the guidance that make the book worth owning.
