Talak Desert
West of the Aïr Mountains, the Talak forms part of the vast desert country of the Sahara. Its sandy expanses give way toward the south to the dry steppe of the Azawagh and the Ighazer basin. Along the western edge of Aïr lies a narrower clay depression also known as the Talak plain. Farther south, the ancient kingdom of Tigidda reached into the desert's margins, where its lands met the Talak and Tamesna.
