This year could simply be called the year of raids and sackings, because the Byzantines lost all of these raids and attacks, by Huns, Lombars, Slavs, and whatnot. However, luckily, with new money coming in from the new Arab Kingdom and the new Sasanian country, the Byzantines are able to sweat it off and restabilize their country.
The Sabeans begin work on the great Church of the East. The Omanis, meanwhile, have finally converted to Christianity.
Oh, and in Spain, the Goths besiege Cordoba, but are forced to abandon the siege after the Byzantines bring in a force of 50,000 to fend off the Goths.
