The idea is to create something like Al-Andalus but in Borneo ruled by Fatimid shia calif.
I started as Fatimid adventurer. A shift to Norse was inevitable to bring there Shia Caliphate through varangian adventure. Kids are tutored to became Beduins. Just in case this doesn't happen, I've given one province to vassal of that culture and order change culture. It will be probably my capital in future. For now I will use the rest of my ruler's life for riding and accumulate gold.
I will probably blend Beduin and Dayak or diverge from first one. I will keep Arabic language and add Austronesian heritage.
Plan was born in my head when I decided to play campaing where goal is to create Brunei.
I just don't have a name for such a culture right now. If anyone has any ideas, I'd be grateful.
