XZR: Hakai no Guuzou

It is the 12th century, and the Muslim world has been split into two warring factions. Meanwhile, Muhammad's disciples are also threatened external forces – in the west the Crusaders; in the east the Mongols. As the Persian assassin Sadler, you are given the task of murdering the Caliph, hopefully saving the future of the Islamic faith in the process, a process which will have implications ranging as far as 800 years into the future. First, however, you must find your three assassin friends and complete a range of quests, for this is an RPG.
