The Treaty of Tyre was a truce called between the Camarilla and clan Assamite in 1496 (though some sources place it in 1493; see the note below on the Convention of Thorns). The Camarilla agreed to call off all hostilities towards the clan ("hold back its Hand from the Full and Ultimate Extinction of Clan Assamite") and stop contracting Assamite assassins, whereas the Assamites agreed to cease their practice of diablerie against Camarilla members (submitting to a blood curse levied by the Tremere to ensure this), dismantle the defences of their stronghold Alamut, and no longer work as assassins.
