Juana the Mad of Castiles' Crown

1506: Castiles, Spain
The artifact was formed by the queen's madness and grief over the loss of her husband, made her ever madder, causing her forced incarceration.

1870: Tordesillas, Spain
The artifact was discovered by agents Rose and Harrison in the queen's final resting place. This was not a normal mission, but rather a preemptive measure taken to impede this artifact to ever be on the prowl. The power of this artifact is greater than any other madness causing artifact.

1871: Warehouse 12
The artifact was adapted by agents Rose and Harrison into the Red Queen's crown in 'Through the Looking-Glass and What Alice Found There'.

Today: Warehouse 13
The artifact survived one excursion of the Warehouse and currently resides in the Grimm Section's Alice Corner.
