Differential Ruby Slipper

A perplexing anomaly

A single ruby slipper

Aboard The Integral

Inside, a cryptic note

Directions and letters

D - 0 R 0 2 1

I am product manager of Integral

I coordinate D-series of chief engineers

But, a ruby slipper?

Is this sabotage?

Vision terrorism?

I investigate the note.

I found the ancient house

Broken walls of glass

Inside

A scarecrow with a TV head

Static

In limp hand, another note

Map, letters

W - 1 C H

I follow map to city edge

All around, a great emerald wall

Infinite unbreakable translucent static emerald wall

Other side of glass wall

Another ruby slipper
