The Even-Tongued Conquest (4081 – 4091 AR), also known (especially in Taldor) as the Even-Tongued Rebellion, began after Aspex the Even-Tongued, a Taldan governor, consolidated the armies under his command, and declared all territory west of the Sellen River as the new nation of Cheliax's. He did this in the wake of a Qadiran invasion of southern Taldor two years earlier, knowing that Taldor would be unable to marshal any serious opposition so far to the west. In the following years, Cheliax annexed the Taldan provinces of Galt and Isger by threat of force, and convinced Andoran and the strix of Devil's Perch to join his cause. The protectorate of Lastwall declared its neutrality during this conflict, effectively becoming an independent nation.
