The Cûno-Halaroi Wars are a series of conflicts which began when the men - or halaroi - of Eänna invaded Eärwa through the Gates of Thayant, a series of fortified passes through the northern Great Kayarsus Mountains. Some historians believe that the Gates of Thayant refer to the Mansion of Siöl, which was located deep under the north-eastern Kayarsus Mountains, and the destruction of Siöl (formerly the strongest of the Mansions before the Battle of Pir Minginnial) marked the beginning of the end for the Nonmen.
The Four Tribes which invaded Eärwa - the Ketyai, Norsirai, Scylvendi and Satyothi - were following the teachings of Angeshraël, the Burned Prophet, and the command of the The Chronicle of the Tusk to throw down the "False Men", or Nonmen. The Nonmen themselves had been weakened by close to a millennium of warfare with the Inchoroi, as well as the loss of their women in the Womb Plague, and were unable to resist the invading hordes of men. In the resulting conflicts, those Mansions which survived the Cûno-Inchoroi Wars were themselves thrown down and destroyed. The sole survivors were Ishterebinth and Cil-Aujas.
The wars lasted for at least four centuries, until Nil’giccas, the King of Ishterebinth, made peace with Cûnwerishau, the God-King of Trysë. The Nonman Tutelage, a prolonged period of peace and alliance between men and Nonmen, began in 555 Year-of-the-Tusk and saw the Nonmen impart knowledge of sorcery - even the Gnosis - to the nascent sorcerous schools. The Tutelage lasted until 825, when it was undone by an assault on the Ûmeri princess Omindalea by a Nonman Siqû.
