Sold matted tail ×3 for 9 gold pieces. "The Guild buys by weight," says Master Pell. "The Guild has always bought by weight."

Lowmoor is a zero-player RPG written in the voice of the old adventure modules. Your adventurer hunts, gains rank, hauls trophies to market, commissions better steel, and descends; the adventure conducts itself the whole way down. Six levels below the town a dragon sleeps upon its hoard, and something older waits below the dragon.

Your counsel is asked at one moment only: choices arrive as sealed letters from the road, and some go to the dice, a d20 rolled in the open against a difficulty class. Leave a letter sealed and it settles itself safely. Watch the descent, fold it to a one-row strip in the corner of a monitor, or close the tab: time passes in the deep while you are gone, and the Guild renders an account of your absence when you return, capped at four hours.

Five arcs, complete and free from end to end. The goblin king falls in the first half hour; the wyrm is an afternoon of leaving it running. Past the wyrm wait a broken stone calling its pieces home, a mage who has watched the whole descent through a thousand small eyes, the offices behind the Court of the Lich, and, below the last door, the debt the Maw was dug to bury. When an arc closes, the game writes your run out as a page of module prose to copy for whoever asks how the descent went.

• Plays in the browser: one file, no install, no account, no telemetry.
• An illustrated bestiary of 132 beasts with the Guild's field notes; a mastery once entered stands for every chronicle after.
• 45 achievements at +1% speed apiece, a prestige Roll of Honour whose nine endowments change how the next run reads, and Guild titles earned at lifetime marks.
• A Trophy Case and Guildhouse that stand across every run; treasures keep their provenance cards.
• Twelve folks, twelve trades, seven schools of magic that cast themselves upon the road, and rarities up to the artefact.
• Autosaves locally, with a paper-friendly save code; sound off by default, with a generative minstrel in the old modes should you wish to hear the descent.
