Ganam / Tadkla
Ganam is a very diverse world with some high technology. The inhabitants, or one group of them, are called the Gaman. Ancient Hainish records refer to it as 'G-14-214-yomo' and also Tadkla. The tale of the first two Ekumen visits is told in the short story "Dancing to Ganam" which appeared in A Fisherman of the Inland Sea. It is described as one of the outermost seedings of the Hainish Expansion, and lost from the human community for five hundred millennia.
