Tékumel
Tékumel is a fantasy world created over several decades by M. A. R. Barker, now a retired professor of Urdu and South Asian Studies. In this world, huge medieval empires contest each other using magic, large armies, and ancient technology. Professor Barker began creating this world in his imaginative play as boy, and as a setting for short stories he wrote as a young man. In a 1984 interview, Barker states that the Tsolyani language and its writing system had taken their present forms by the time he was twelve years old -- long before his professional career as a linguist began.
