And yet, we know that it got toasted by the Lucifer- errr, by some Shivans. I wonder what kind of damage would be detectable after so very long (8k years?) that distinguished it as Shivan battle scars.
I dunno. You do enough damage to raze an entire planetary surface from orbit, I think that's going to leave a lasting mark.
Heck, look at the chunk of debris that hit Mars and created Tythonus Chasma (the largest canyon in the solar system). Its age is estimated, conservatively, at over 500 million
years. And that was just a rock
hitting once. The Shivans steamrolled an entire planetary surface.
On sheerest speculation, let's say the Shivans used high energy weaponry to crack the mantle in several places. That would create distinct scarring that would outlast the resulting cataclysm.
