The highly popular Turkish TV drama series Diriliş: Ertuğrul has Ertuğrul and his Kayı tribe fighting the Templars based in a "castle" which apparently should be identified with the real-world Bagras.
Thing is: the Templars were only active in what is in modern terms south and south-eastern Turkey (according to wiki) while the Kayı and their successor Ottomans lived and fought in northwestern Turkey.
Am I missing some connection here or is the whole plot just pure artistic license?
