Y Ddraig Goch
The Red Dragon of Wales — one of two dragons sleeping in an underground lake beneath King Vortigern's tower. Nothing built on top of unintegrated dragons will stand.

The Red Dragon on the Welsh flag descends from the tale of Dinas Emrys: King Vortigern's tower keeps collapsing until the boy Merlin (Myrddin Emrys) reveals why — beneath the hill, in an underground lake, two dragons sleep, red and white, and their subterranean struggle shakes the foundations. When unearthed, they fight; the red at last prevails. Nothing built on top of unintegrated dragons will stand. It is the oldest political psychology lesson in Europe.
The SGE Reading
Shadow stage at the *civic* scale: what a nation refuses to know about its own foundations, the foundations will keep telling it.
Canon Resonance
Doña Flor's marble eggs, in political dress: the sleeping dragons a whole culture keeps building on top of.
A Micro-Practice
Name one thing in your life whose "tower keeps collapsing." Ask: *what pair of dragons am I refusing to unearth beneath it?*
