[@Willy Vereb]I don't see much problem with it. It's been a while, it's fair to say that human records of them, if they even had any, were lost over time. Or the damage to Mars caused a great loss of most traces of them. It's easy to explain why information is lacking, and even your NS says the non-Martians don't even have much left from them despite being directly descended from them. If someone wants to use it then it's fine, but if not then they're easily forgotten.

The Precursor Legend is kind of the equivalent of religion for the Sarmakth. They have some findings and old obscure recordings made shortly after the great war which devastated Mars but there's no hard proof on anything. The idea their forced evolution is to adapt to their environment could be also a sham (who the hell thinks floating brains are the most survivable?) or perhaps the Sarmakth are wrong and they are just yet another creations of the Precursors. Anything is possible. For the record most of their propaganda and feeling of superiority uses the basis that they are the direct evolution of Precursors and all life belongs to them by proxy. If this theory is invalidated that could make quite a schizm between the Sarmakth.

So yeah, I see lot of fun potential in it.
