In A Grimm Warning, the soldiers of the Grande Armée present their general with a mirror found in a ransacked village in the Eastern Kingdom. It is a Mirror of Truth, revealing one's true self when one stands before it.
The mirror is square and heavy, with a thick golden frame with floral carvings and very pure glass.
When General Marquis looks into the mirror, he sees a weak little boy. "The boy was dreadfully skinny, flithy, and he trembled; he was a starving and scared peasant. His clothes were covered in holes and tears and he didn't have any shoes. His left eye was swollen shut from a severe beating."
Hating to be reminded of his past, the general orders the mirror to be destroyed.
