Hey, i want to make the Di'amat and the Erythraia province. I will begin to study Ethiopology in Octobre and i will have acess to a library and educated professors. So if you can give me several months to research i will give you the descriptions.

Btw., why you choosed Aksum as the provincial capital of Di' amat? There are no evidences that this city even existed in 272 bc and it's rise to importance began in the 1'st century AD. I would presume Yeha as the capital of the former Di'amat kingdom.
