the following selection of new eastern factions i hope to create
the abbasid caliphate ( baghdad province)
zangids
hammadans
idal
hillah
dirbend
shirvan
ps any opinions id love to hear them thinking of more eastern factions let me hear them, most of these factions are located towards the region of azerbajan, iran, iraq and kuwait, iam not an expert at the greek-byzantinian vassals so it would be great to hear ya , i hope with these new additions you modders out there would raise the courage to create any more mercenries or totally new units that are relevant to these factions.
psss if ya don't know much about these factions the following sites i recommend besides wikipedia
