I can't wait to play this. Clearly, you've researched the subject throughly.

Although, with all due respect, there are a couple of things that i would like to bring to your attention.

Firstly, i think it's Al-Nizar rather than An-Nizar. It could be that people think it's an N because when arabs say Al- followed by a name, they tend to stick them together. The L is muted and the N elongated.

Secondly, i noticed you have referred to them as Hashashin and Hashishin. The former would be the correct one. The singular being Hashash - One who smokes Hashish. Regularly. :)
