I don't like the Nox being an offshoot of the Ancients. Linguistically (as per Torment of Tantalus), it doesn't make any sense.
They have to be predakaran, which makes them ancient. They are not from Earth, and have advanced powers and incredibly advanced technology, they can only be ancient or a derivation of Ancient leftover from before Earth humans reevolved, most likely guided by the nox. The other option is that they are Lantians which left Earth 10,000 years ago, in which case they would still be ancient, but from a later period.
