Regeneration In Process
I suggest you all refocus on the business of arguing over the more general details of the languages (such as its representation)
We'll adapt someone else's alphabet later. It's situational.
your mythologies
Too early to develop anything overtly complex, so let's take a basic polytheism with particular reverence for the gods of the Sun (Dilaca) and the Moon (Biaga). Chthonic deities are curiously insignificant/absent in everyday worship (in polite society, anyway), though some of their attributes have gradually moved to the other gods.
The cosmogony and theogony is pretty basic as well: Bul Muduri, the ancient chthonic deity, had spawned the Uda Sebe, the main gods of the Pegi Rente, who eventually slew it, made the world out of its body and retired to the upper level of the world after creating the humans to feed and serve them in the mortal world. They did not at all completely withdraw from the world, though; as per the principle of "as below, so above", they still move around to herd their mythical flock, hunt equally mythical beasts (including leftover chthonic children of Bul Muduri that hide out in the dark corners of the world) and punish humans for all kinds of things, as is only proper. There will likely be retcons, but that's okay, Babylonians did that too.
what kind of terrain you're interested in
We did that already, didn't we?

who you think is most likely similar.
Samas of erez87 sound pretty similar, while the Arozi of SwissEmpire are totally the leftover chthonic spawn of Bul Muduri whom all the good humans are obliged to enslave and generally abuse. Okay, that last bit is purely hypothetical, but if he's anywhere near we should keep that convenient association of Bul Muduri with water in mind.

Why would I assist you in figuring out how big the planet is to any capacity?.![]()
Well, giving us some idea of how big a given area is supposed to be might be useful (if only for comparison with real world equivalents), though probably more so later on.
