Petruska was the first queen of Krontep.
When Moriah found out about his wife's infidelity, he beat her nearly to death. She then committed suicide in despair.
Moriah used the time-space tunnel she developed to travel to 1950s Earth. He founded the Petruska Psychiatric Institution (naming it after her) and created the Toys, hoping to recreate his wife. (PROSE: Bad Therapy)
