Encounters, lore, and maps all connected

Encounters

Encounter pages from ready building blocks

Drop in read-aloud text, monsters, skill checks, and loot. Each block formats itself, so the scene is table-ready as you type.

A monsters section holding a goblin's stat block
An NPC section showing Maera Thistledown's sheet
A skill check section with its DC and success and failure text
A painted region map with pins on its villages, forest and mine

Maps

Maps that open your world

Drop a pin and it opens an encounter or lore page. Regions drill down to cities, cities to rooms.

Lore

One lore library

NPCs, factions, and places all live in one library. Reference any of them from any scene in a click.

Old Sallow, hermit of the Briarwood
The Dawnshrine, a temple in the lore library
The Emberheart Amulet in the item library

The Dawnshrine

⛬ Temple

A round shrine of white stone on the bare hill east of the river, raised to the Dawnmother when Bramblebrook was a camp of tents. The vigil-flame went out four winters ago and nobody climbed the hill to relight it.

The vigil

A flame kept burning from dusk to dawn, once, with the keeper awake beside it. What the vigil kept away was never written down.
