After the Vlandians last month, Mount and blade 2: Banner announced its latest faction: Aserai. Based on the thriving tribes of the Arab conquests of the seventh and eighth centuries, a comprehensive blog post from the TaleWorlds developer described their history, fighting and combat capabilities.
Inside, we know that Aserai consists of small factions, like all Bannerlord cultures. Their size and institutions are not necessarily consistent with Bannerlord's political system; we are told that this means that their southern desert countryside is "difficult to dominate and dangerous to. pass".
