Oh, yes, the guardian doesn't want you to use the purifier that's clear. I'm talking about the narrative at the end when you conclude that you have been permanently altered.
I mean the first meeting with the Guardian that happens on day 3 or so. They show up saying "I came just in time. You were transforming . . . "
I think the guardian tadpoled us, let us cook for three days and then stopped the transformation so we just altered enough to be receptive to it's manipulations. At that point our brain is at least 1/8 illithid.
