So far, I've watched 24 episodes of it, and visually, the series is incredibly powerful and truly enjoyable to watch as a viewer. However, when it comes to historical series, I'm always interested in hearing and seeing historical truths. This series, in terms of authenticity, is purely a fabrication. Many of the events depicted throughout the series are not compatible with recorded history, and with a simple search in historical books or even Google, you can realize this issue. For example, Nizam al-Mulk was born in 1018, Hasan Sabbah in 1050, and Omar Khayyam in 1048. So, it's impossible for these three individuals to be of the same age and make a pact with each other in their youth. Many other events in the series are also not in line with reality.
