A Foundry VTT module (V13/V14) built for play-by-post games in the Powered by the Apocalypse tradition — or any other system. It is not tied to any ruleset.
The idea: a player drops in when they can, writes their bit, and leaves. The GM gathers it all up, narrates, and moves the story on.
Thread. A scene or place where play happens. Several can run at once (some at the tavern, others in the forest), each with its own participants and its own pace. Each thread is a Foundry JournalEntry and each post one of its pages, so everything is searchable, exportable and backed up with the native tools.
By rounds is the recommended mode for play-by-post: it stops the whole group from being blocked waiting on the slowest player.
Voices. Every post is made in the name of a character, with their portrait. The GM can switch NPC between one post and the next to play several at once. Anyone can mark a post as out of character: those don't consume the round and are never blocked, so coordination is always possible.
Visibility. Threads can be public, private (participants only) or hidden (GM only). Inside a public thread you can also send secret posts to specific people.
Drafts. What you write is saved as you type, even if you can't post yet — write now, post when the round opens.
Chronicle. Scene summaries and highlighted moments build a timeline of the campaign, with full-text search across every post and export to Markdown.
