Hmmm...not sure, but here's some questions that I think might help me:
It's clear that there's supposed to be some relationship to this dead god and their own progeny, but what is it that they did or did not do to feel guilty or regretful?
Do the duo of mindwalkers really grasp the abstract meaning of the things they observe and engage with in order to cleanse the dead god?
What really constitutes cleansing in this mindscape? Do things fade away or do they reconcile and change for the better?
