Rowena's journals

Rowena's journals are a series of journals created by witch Rowena MacLeod chronicling her spellwork over the course of her life.

History
The journals were written by Rowena MacLeod over the course of her centuries-long life. They chronicled her spellwork, including the various spells she created and used. One spell was the Spirit Resurrection Spell Rowena had been creating to resurrect Mary Winchester.

In 2019, while casting the Sanetur Acre Vulnus, Rowena had Sam use one of her journals as a reference for his part in the spell as her assistant.

Following Rowena's death, Sam traveled to her apartment in search of Rowena's magical stash, her journals in particular, to find out how to create a Soul Catcher. The ghost of Eileen Leahy helped Sam find a hidden room where the stash was hidden, saddening Sam with the reminder of his friend. While Sam leafed through one of the journals, a loose page fell out containing the spell Rowena had been creating to resurrect Mary. Sam realized he could use it to bring back Eileen, but came into conflict with the Witch Mother and Emily who sought to use the spell to resurrect Jacinda instead. After the witches were dealt with, Sam brought the journals and the rest of Rowena's stash back to the Men of Letters bunker.
