Elesh Norn imagines her Orthodoxy as purity beyond organic weakness. Ashiok turns that certainty into a nightmare in which human flesh grows through her immaculate surroundings. Elspeth's likeness becomes part of the disturbance, linking Norn's fear to someone who escaped Phyrexia.
Norn does not simply submit to the intrusion. She brings the collective's presence into the dream and drives against Ashiok's work. Her response demonstrates real power while failing to erase the fact that she could be frightened.
The encounter is not Elspeth physically invading the Basilica, and its grotesque transformations are not a report of the waking courtyard. It is a test of Norn's mind. The leader who defines every other creature as flawed cannot safely admit what the test reveals about herself.
