Tagora

Tagora (Тагора): the home planet of Tagorians, a lizard-like alien race, the first one Earth's ever contacted with. It is mentioned in An Attempt to Escape that there is a human resident (or spy) on Tagora whose name is presumably Benny Durov (Бенни Дуров) and he is a progressor working under cover to study Tagorian technology. Discovered in the end of 21st century although a full scaled contact was established in 2122 AD.
