The Landmark Universe is an open-source RPG currently under development by Simon Kirby on OSSH and PDSH. Set predominantly in the fictional city of Chamberlain, USA, it combines both public domain and open source characters in a storyline spanning over three hundred years. At the present time, the game employs ten main characters based on well-known heroic archetypes. When finished, it will include detailed profiles, histories, timelines and storyarcs. All Landmark properties are available under CC-BY-SA 3.0; artists and writers are most welcome to reuse, develop, and contribute their own comic strips based on Landmark characters.
