The Nizari Ismaili State, the medieval order founded by Hasan-i Sabbah, popularly called the Assassins.
The engine confirms the group was real but breaks the chain claiming their secret knowledge passed to the Templars.
This Shia order captured the fortress of Alamut in 1090 and carried out targeted political assassinations across the Levant during the Crusades until the Mongols destroyed them in 1256. A book cites them as a real foundation, but the engine notes they were isolated in time and place with no documented teaching passed to the Templars. It also flags that the 'hashish-eater to assassin' drug legend is a hostile European fabrication (per Daftary's 'The Assassin Legends'), not found in medieval Islamic sources.
The engine keeps the real history but deliberately fails the claimed occult-transmission chain — a case of separating a genuine substrate from a myth built on top of it.
