The offer is natural. Pretty much how Irajinad categorizes things:
A) The state gladly accepts and swears complete loyalty. They become an Honorable Emirate.
B) The state accepts membership, but wishes to iron things out first or have some time (allotted 10-20 years) to decide if it will swear complete loyalty. In this period, IE forces occupy the area, and all actions are overseen by the Honorable Emirates. If things are stable and acceptable, they may either swear complete loyalty and become an Honorable Emirate, or may be unsure and become a normal Emirate.
C) The state does not guarantee to be outright loyal, but will still exist and submit to higher governance, including Iraji-appointed officials. They become a normsl Emirate.
D) The state refuses outright, and continues fighting even after victory of the first capitol (Where capitol has not moved so that fighting may continue), the state becomes IE territory, which means it is target to islamic crusades, higher taxes, pretty much pressure on the leaders to rethink loyalty.
Ezbatans, becoming increasingly frightened by the mighty and enormous Islamic Empire, shake in terror, but attempt to band together.
The five-state alliance in Ezbátu sends an envoy to the IE, proposing a ceasefire agreement for a hundred years, along with trade (offering gold, gems and ancient relics gathered from the high point of The Confederacy, The Erinamese Empire, and even before, as well as some international goods from Zesisoter.)
Some of the independent states begin to absorb into the larger five-state group, seeking security in numbers and amongst friends.
Sorry I missed the NSIs. I'll return with them later.
