Before Dorothy

Blew in with her breasts bound
And her crisp dress from the cyclonic orphanage
There were a balance of witches, good and bad
The orangeade Sun rose every day on too-green petals reflected

Back and forth between denizens who were happy to accept
Any wizard who would at least try to run the wheels and fire
While they buffed the hollow tin bodies of men,
Their straw-man arguments perfected.

They didn’t suspect that the Destroyer and her dog could kill commerce
One critical quadrant of magic would be snuffed out by just her house
No one knew about the fields of coin until her arrival
The collapse of the emerald gates allowed regression

After Dorothy

Desperate to live, the skewed witches remained, eating children
But only those without parents, or with poor parents
The Good Witch captured them in bubbles but would not
Participate in the magical deaths.  Her own sister was liquified.

GW spent considerable time brainwashing Dorothy;
In the end she managed to ensnare the bitch and exile
Her to another dimension, in a polite way.
They, as Oz, wouldn’t survive any return visitation.
