RULES, SOURCES & SYSTEMS
How and why the Eshyra rules pack is built
The engineering story behind the pack: a source-grounded rules compiler, executable curation, and the boundary between an AI Dungeon Master and a deterministic rules engine.
Read the essay →The project
IN DEVELOPMENTEshyra is a campaign engine for long-running fantasy play: it remembers prior events, tracks structured game state, adjudicates rules through deterministic tools, and sustains a tabletop-like solo or small-group experience entirely through text.
Eshyra itself is early pre-release and under construction. There is no sign-up yet. In the meantime, the project has produced something useful on its own: a structured, openly licensed D&D 5e SRD rules pack you can download and use today.
Follow development on GitHub ↗D&D 5e SRD 5.1 rules pack
A structured, machine-friendly representation of the System Reference Document 5.1, extracted by Eshyra's deterministic importer into a single JSON records file with per-record provenance. Useful for tools, bots, search indexes, and other tabletop software.
How and why this rules pack is built — the engineering story behind the pack: a source-grounded rules compiler, executable curation, and the boundary between an AI Dungeon Master and a deterministic rules engine.
