Afansevan

Afansevan is a branch of the Indo-European language family spoken by about 10 million people inside our world's California, Nevada, Arizona, and Western Mexico that takes place in the same universe as American Turkic and has no official status within the Kyrgyz Khaganate, although it is an official language alongside American Turkic in the provinces that formerly constituted the Californian Empire (which can be shown in the map below). This article will be of Imperial Afansevan, which was spoken during the times of the Californian Empire and is the direct ancestor to all modern Afansevan varieties (Kinda like how Latin diverged into the Romance languages). The Imperial Afansevan variety in this article will be the language as it is in the 14th century (and I'll be using the term "Afansevan" will be used to refer to Imperial Afansevan from now on).

History
The Afansevans are the descendants of Indo-European speaking slaves brought to the New World during the Great Migration. By the turn of the 10th century, the Afansevans broke free, migrated southwards, and settled in OTL's Los Angeles, forming the Californian Empire. The Californian Empire then quickly conquered and subjugated all of California under one banner, later expanding into OTLL's Nevada, Arizona, and the Baja California peninsula. Later expansions occurred along the Gulf of California and the Western coast of Mexico. The Californian Empire also formed an alliance with the Kyrgyz Khaganate during the latter expansion, eventually helping the southern warlord state win the Kyrgyz Civil War.

In 1508, the Californian Emperor married a Kyrgyz princess, having a son together. He held the Kyrgyz throne first in 1526 after the reigning Khagan died without any children, followed by the Californian throne in 1531 following the death of his father, ruling the two monarchies under a personal union. He wanted to unify the two countries as one state rather than keep the personal union to counter Vinland's reign of terror across the Canadian Shield, and to expand trade with China via the Pacific Rim, so he started integrating the two countries into a Pacific superstate. By 1539, the Californian Empire was no more, and its former territory was used as a strategic point for Kyrgyzia to colonize Hawaii and other Polynesian islands, which exponentially expanded the trade with the Old World via the Pacific Ocean. It, along with the discovery of gold in the ashes of the Californian Empire in the turn of the 16th century, which attracted Turkic-speaking settlers to move to California at the expense of the Afansevans, paves the way for Kyrgyzia becoming an economic powerhouse (and having 3x the GDP of all of Europe combined by the 18th century).

Tone
Afansevan has developed a six-tone system following the loss of plosives in coda position (other than when there are two plosives in the coda, where the first one is lost, which makes tone phonemic). Note that the vowel in this example is , and that the tone occurs at the end of the syllable.

Phonotactics
Afansevan's syllable structure is (C)(C)V(C)(C), where C is any consonant, and V is any vowel, , or . Consonant clusters made of two plosives are not allowed in the coda. All permitted consonant clusters in the onset are any obstruent (other than ) followed by  or .  and  can serve as the nucleus of a syllable, in that case they are pronounced as syllabic consonants. Voiced and voiceless obstruents (other than ) are not allowed to go together in coda-onset clusters, in that case, the last one assimilates the other ones in voicing (e.g. /pzf/>/psf/). Also, voiced obstruents (other than ) are not allowed to end a word, as they become voiceless in that environment.
