also where is quintessence
i think you get quintessence either when you can make the pchre genesis, ultraviolet nebula and crimson singularity T3 lights, or from a blueprint.
though i can't remember which cache would have it.
i got access to it pretty much by accident.
i messed with the files since i got way too bored waiting for resources to pile up, so i removed a digit from the fractured void sector cost and pristine light conversion cost. so i suddenly had enough light to buy ALL the sectors too rings further and pretty much all caches are in that region.
