House Telvanni is one of the Great Houses of Morrowind. They refused to join the Ebonheart Pact, partially on the grounds of slavery, as the Argonians, which make up a large proportion of their slaves, were granted equal membership of the Pact and all Argonian slaves were to be released.
The affairs of the House are run by the Telvanni Council, which consists of five powerful Telvanni wizards, formally led by Archmagister Nelos Otheri. However, the councilors prefer not to be disturbed and do not usually act directly, but rather through intermediaries known as Mouths, who attend the council sessions in Sadrith Mora on their behalf.
