Supernatural is quite the popular series already with it finally reaching it's tenth season. With the last spin off attempt being unsuccessful it's only obvious that another spin off shall be attempted soon.

With the Men of Letters becoming increasingly popular lore beneath the series its only natural fans would want more. So with this I ask that we get a Supernatural: Men of Letters spinoff series. Which could star The Winchester's unknown grandfather and his years in the Men of Letters.

Interest in this show would be phenomenal since many people shall be interested in uncovering more lore from the original series. So please make this happen. Let's see a spin off that can succeed just as well as the original series.
