It's the Vellari Exatai, not the Vellari Rashai. Oracular redistribution of resources would not go over well with the Accans.
I also noticed the poor Shield Princes didn't make it onto your list. Gotta feel for those guys.
Yes, I am extremely interested in securing a player for the
Tephran Exatai. Please PM or visitor message me if you're interested in knowing more. Overall, they're extremely traditionalist Vedai Satar, though ethnically mostly Vithana and Xieni, that identity has pretty much been subsumed by the Vedai identity among the upper classes. They have a very strong alliance with the Vischa Exatai, so prospective players could most likely count on a friend in Golden1Knight.
They follow orthodox (Vedai) Ardavan, and are distributed into a variety of semi-autonomous princedoms that usually owe fealty to the High Prince of the Wind. (The Satar word for wind, teph, is what gives this Exatai its colloquial name.) How much support they offer is generally dependent on how much exatas the High Prince has; if he is acclaimed Redeemer (which he is currently not,) this vastly enhances his local prestige. They are fond of raiding and trading, and while mostly a rural people ruling over vast tracts of land, they have several ancient and impressive fortress cities under their control, most notably Arastephaion in the far south, and Mareva, their capital.
Their main enemies are the Zalkephai Rashai (played by Crezth), the NPC Exalai Sartashai, and the Vellari, though the latter is not due to conflicts over territory but more ideological, cultural and historical differences. Relations are likely good with Tin Tan Tar and the High Oracles of Siaxis, as well as at least passably good with the Ashelai.

One important thing I would like all of the Satar players to consider is that the Redeemer title still exists but for only one man in the world at a time, and that the Shield Prince of Alusille is still technically the de jure liege of the Ashelai, Vellari, Tephrans, and etc. until he dies, and the High Oracle chooses a new Redeemer. [This system was established in a now 250 year old treaty called the
Matshav.] Effectively this means nothing, as the ceremonial "tribute" the High Princes send the Redeemer is just that, a ceremonial gift, though an effective High Prince could in theory gain support from abroad by controlling the Redeemer title if others stood to gain from it.
One reason the aged Shield Prince (Exalai Sartas) holds the title is for successfully defending his lands against the hated Zalkephai where the Tephrans failed and lost control of Sartasion, again. Also, the Princedom of the Shield is ancient, prosperous and extremely prestigious, despite its small size. Historically over the ET the Redeemer title has mostly bounced between the Tephrans and the Shield Princes, mostly because the Vellari are usually interested in doing Other Things™ with their money and the Ashelai haven't made much of an impression yet.
Obviously you have no obligation to support whoever the Redeemer happens to be, though it might be seen as extremely dishonorable to refuse a Redeemer's call to war against an enemy who does not follow the God-In-Potentiality. Of course, patronizing Siaxis and the High Oracle could be a valuable use of your time and money if you're interested in your dynasty getting the title when the previous owner dies, though plenty of great High Princes have got along fine without being acclaimed Redeemer.
Declaring yourself Redeemer without Siaxis' approval is not done. You could do it, but it would have potentially grave consequences for religious and foreign relations with other Satar, so people tend to stick to High Prince and try to convince Siaxis to acclaim them Redeemer, rather than run the risk of defying the High Oracle and having him or her call all the other Satar to oppose the wayward heretic.
Golden, I'm actually not sure how the Vischa fit into this equation, if they still declare their ruler Redeemer or have fallen in line with the High Prince/Redeemer dichotomy that evolved over the ET. It's largely up to you, though I suspect the Tephrans would have enforced the eastern rule when they put the current dynasty on the throne.
