purgatory soul

Despite their best efforts, Dean, Sam and Bobby fail to stop Castiel, who uses the Purgatory souls to elevate himself to a god-like level in the sixth season finale.

Usually white topped with a cross, they contain religious statues or images, often in "azulejo" (Portuguese tile) representing saints, the Virgin Mary, God or an allegory to Purgatory souls.

While the cult has a general Christian-Catholic frame (as the "pezzentelle" are usually identified as Purgatory souls), many of its elements are rather pagan in nature, so that it can be classified as a syncretic cult.

They learn how to access Purgatory in the season finale, but Castiel reveals that he has no intentions of letting Crowley have any of the Purgatory souls, thus Crowley forms an alliance with Castiel's enemy Raphael.
