Mental contamination is mutual.
At least that's how it appears to Gawain.
Based on the experimental references provided by the Eternal Sleepers and the technical data left by the Defier, Gawain can almost determine the birth process of gods is related to mortal beliefs, or more accurately, it's the collective human thought projected onto a deep dimension of this world, leading to the birth of gods. If this model holds true, the process of dealing face-to-face with gods is essentially a sanity-dropping interaction—mutual contamination.
Gods' knowledge will uncontrollably contaminate any mind it connects with (Gawain doesn't currently know how to block this connection), and conversely, those minds that establish connections with gods inevitably exert a reverse influence. Yet one thing is clear: a normal mind is simply incomparable to that of a god, turning the sanity-dropping process into a one-sided erosion.
