An unofficial D&D 5e (2014 ruleset / SRD 5.1) Dungeon Master skill for [Claude Code](https://claude.ai/code) — persistent campaigns, full 5e mechanics, and an optional cinematic display companion that streams typewriter narration, dice rolls, and live character stats to any screen — TV via Chromecast, tablet, phone, or second monitor — while players submit their actions from a phone or tablet.

Built for groups who want a real DM experience without needing one at the table.
