Things never change do they? I kept telling the boys over and over again, I would say, 'We can stop all this, we could rid the world of monsters once and for all, if we just put our minds to it.' But 'Oh no,' they said, 'no, no, no, it's not our place, we're here to study, we're here to catalog.' – Magnus, 9.16 Blade Runners

History

Cuthbert Sinclair was a former member of the Men of Letters, he was named "Master of Spells" soon after his initiation, and went on to design most of the warding that was used in the Bunker, he as also a mentor to Henry Winchester. Eventually, his proposed projects for the Men of Letters in his last few years as a part of the organization were rejected by the leadership for being eccentric and irresponsible. This eventually lead to his complete separation from the Men of Letters in April 1956. After the separation Cuthbert took the name "Magnus" and began collecting supernatural paraphernalia, spells, as well keeping a "zoo" of monsters in a magically hidden fortress.

With the help of Crowley, Sam and Dean are able to locate Sinclair's fortress. Once there they reveal themselves as Henry Winchester's grandsons, and Men of Letters, Magnus then creates a entrance for them to enter and goes about testing them against two vampires from his zoo to see "what they are made of." Once the Winchesters kill the vampires, Magnus sits down with them to hear them out. They relay to him the threat of Abaddon and that they need the First Blade to take her down, upon seeing the Mark of Cain on Dean's arm, Magnus uses a spell to send Sam back to the outside, while he tries to sell Dean on becoming apart of his collection and living forever.

When Dean refuses, Magnus takes to using magic to get Dean to be compliant and places the First Blade in his hand to see what would happen. When Sam and Crowely find a spell that will gain them entrance to fortress, Magnus attempts to use Sam against Dean to make Dean see things his way. While Magnus is torturing Sam, Crowley is able to release Dean from his chains, allowing him to grab the First Blade and decapitates Magnus.
