The Mamluks were slave warriors during the dark ages that fought for the sultans of Egypt and Arabia. They were taken from other lands as children and raised to fight. The thought was that a sultan could trust them because they were not local. These guys got so powerful that for a long while they even overcame thier masters and ruled Egypt as sultan.
I want to do a story about a warrior born a slave who became a sultan. He has trusted warrior allies, wives and servants. He is a better warrior than a politician and ends up betrayed. He has to flee the city with what is left of his army and harem. For better or for worse they must work together to survive in a harsh world with few allies.
Now in terms of setting I could see lots of options. Obviously we could go historical. But we could also pick a fantasy setting with a game of thrones vibe. I even have notes on a more modern day criminal reality and a sci-fi planetary romance setting.
So I am not a huge fan of investing large time in world creation until I know I have a group of interested folks. This might look a little light on detail at the moment but I promise one we get this thing going the flood gates will open. I am not just looking for players but collaborators.
Young harem wives (some are there for only thier looks, others are the daughters of past enemies)
Head wife (slightly older and the sultans first love)
Prince (the Sultans teenage son)
Mamluks (a small group of trusted fighters)
Advisor (a foreign man who helps the sultan)
If I get two or three interested we can build the world together, then I will GM and play the Sultan)
