Níðhöggr
The dragon who gnaws the deepest root of Yggdrasil while an eagle sits in the crown — and a squirrel carries insults between them.

At the roots of Yggdrasil, the World Tree, coils Níðhöggr — the dragon who gnaws the deepest root, while an eagle sits in the crown, and a squirrel, Ratatoskr, runs up and down the trunk carrying insults between them. It is the oldest comic image of the mind: the heights and the depths at war, with chattering thought as the messenger.
The SGE Reading
Shadow stage as *chronic corrosion*: the slow, patient gnawing at what holds you up, fueled by the mind's endless commuting between crown and root.
Canon Resonance
A map of every long-term self-sabotage the nine women meet in themselves.
A Micro-Practice
For one full day, notice each time you carry an insult (received or generated) up or down inside yourself. You do not have to stop; just count. At day's end the number itself will teach you something.
