World Anvil is an online worldbuilding community and platform for authors, game masters, artists, and anyone who enjoys creating fictional worlds. Its tools help creators develop, organize, preserve, and share settings, stories, characters, places, and other worldbuilding material. The site also supports role-playing campaigns and community participation through discussion boards, articles, and creative events.

Hallowed Legacy is one example of a setting presented on World Anvil. Developed across generations of storytelling and gaming, it brings together interconnected realms, mythic histories, characters, and campaigns for systems including Pathfinder and Dungeons & Dragons. Its creators use the platform to organize decades of notes and adventures and share the setting with players around the world.

Alongside its worldbuilding tools, World Anvil offers resources such as random generators, writing prompts, a podcast, a blog, streaming events, and major community challenges. Visitors can explore membership options, gift a membership, join the community, and browse the company’s shop for gifts and World Anvil gear.
