Fablerift

A text RPG in the classic MUD tradition, played live against one shared server. Seven regions of forest, coast, desert and frozen peak, each with its own weather and a day/night cycle that changes which creatures come out. Gathering, crafting and cooking feed into combat; a party can clear three instanced dungeons with party scaling and bosses that telegraph their heaviest blows. Classes have their own abilities with mana and cooldowns. Players trade with each other, join guilds, send mail with items attached, claim a plot of land, and follow a five-chapter story to a final boss.

Command-driven and keyboard-only, with screen-reader, large-text, ASCII-only and color-free modes built in. A new-player journey and a `hint` command show you what to do next.

Nothing to install: open the play link, choose a name and a password, and you are in the world. The server itself is MIT-licensed and self-hostable, with an embedded web admin panel, so you can run your own world over telnet or SSH and invite people to it.

Chat is unmoderated in real time and player-generated, so expect the usual online-multiplayer content warnings.
