Leila

Leila was a Templar agent operating in Egypt. In 1341, she infiltrated the Egyptian Sultan Al-Nasir Muhammad's palace as a servant. She murdered the Sultan by slitting his throat, in the name of the 'Templar's fight against oppression', but was captured while making her escape from the Sultan's palace. She later shared her cell with the Assassin Numa Al'Khamsin.
