The Marain alphabet was invented by Iain M. Banks to write his
constructed language with the same name, which appears in his 'Culture'
series of novels, such as The Player of Games
Marain was designed by the Culture's hyperintelligent Minds, self-conscious
entities that have evolved in machines such as starships, planets and orbitals
originally built by humanoid species but which have outsmarted their creators by
several orders of magnitude.
