African Romance spoken around Carthage is called Ifriqian in this timeline and has (or is supposed to have) a large Punic substratum. On the other hand, Moritanian has a Berber substratum.
Part 12: The heart of Asia , along the Great Silk Road
What was going on in Central Asia? Well after the fall of Sassanid Persia and the Hephtalites (who ruled Central Asia until 670s), various small principalities emerged at the southern coast of the Caspian Sea. The Karen dynasty assumed control of the the former satrapy of Dihistan and Margiana (Merv), but also Abarshahr and Khorasan., while most of southeastern Iran remained ruled by the Mihran dynasty.
Central Asia was divided into two realms, Bactria/Tokharistan at the upper Oxus Basin (Tajikistan and adjacent areas of Afghanistan) and Sogdia (central Uzbekistan).
Sistan was also governed by the Mihran dynasty, while Afghanistan was balkanised.
Transoxiana was increasingly Turkified, with a Sogdian and Bactrian languages surviving. Farghana was a major urban center by this time.The Bactrian and Sogdian languages have reached a high literal standard. These areas are cosmopolitan with merchants bringing new ideas, with people and ideas originating from China to Rhomania. The area does not have a strong religious identity, but Bactria is more Zoroastrian-Manichean while Sogdia is more Nestorian-Buddhist but still with substantial Manichean influence.
Central Asia is now becoming the last hotbed for Manicheism. (However I am uncertain of the long term viability of a Manichean-based society since Manicheism believes that sexuality and earthly goods are bad, hence slow population growth implying the realm could get easier overwhelmed by more dynamic tribes)
The area around Kabul was ruled by the so-called Kabul Shahis - Turkic dynasty of Hindu religion, while the south was ruled by the Zunbil dynasty.
The primary religion in the Tarim Basin and and and Bactria remained Manicheism, while Sogdia was Zoroastrian. Afghanistan wand Pakistan were in the Hindu sphere. The Church of the east had some successes in converting the Turkic peoples, but Central Asia remained until 900s a mishmash of Nestorianism, Manicheism, Zoroastrianism, Buddhism and Tengrism.
The Mihran dynasty, controlling the eastern half of Iran and also Sistan and Balochistan is considered to be the true successor of Sassanid Persia. The atention of the Mihran dynasty in the 7th century is to reclaim the lands of the former Sassanid empire.
So basically a large empire, the Mihranids, and a handful of kingdoms around it. In the following century (8th century) the Mihranids would have consolidated their positions and start reclaiming former Iranian lands to their west and east
