As seen in the much bigger Au Ra thread here:

The naming rules for both clans have been finalized and work is being done fleshing out the lore behind it all. Things will be somewhat similar to what was done with the Hyur (drawing from historic names) but the with the regional and linguistic roots being completely different. Surnames will also feature a special set of rules that can be followed to the T, or slightly modified if a player wants to be adventurous.

I will be adding a detailed (sticky) explanation right here to the forums once Yoshi-P has given me the green light...which hopefully will be sooner than later!
We haven't gotten any more information than that on the timing of the names, though I imagine we'd probably get that after we get some actual background information about them.
