Greeting Bubba. I have always thought as you do now, but found the only way to actually make a large impact on the lore of the game is to join the team.
For the information you are seeking, I assure you there is text already written and coming. It is quite a process to make sure there are no conflicts with existing ingame info and internal reference documents.
After looking over your post and what you ask asking for, I can give you a few brief bits of info that are already known publicly, but not yet in an easy to digest form (but will be).
Kran do not have their own unique language, but share a common one with Lemurs. This is now the 'Common' tongue spoken ingame today. Due to their long history with the Lemur and their natures, the two races have almost always existed in friendship, and have been the 'glue' that helped bring the other races together. That history will be expanded on as well. You can see the basic Kran art style in the design of Gugrontid. Religion, obviously, is predominantly Talad, and the worship style is not unique to Kran. There will be books similar to the Laanx book ingame now to further explain the religion, Soon(TM). Education will be similar for all races.
I know that is not much, but I hope it assures you that we are working towards bringing you the information you desire.
By the way, Devs still roleplay... we just get bigger toys.
