Supernatural introduced a brand new world of mythology in its latest episode, revealing that Sam and Dean’s grandfather, Henry Winchester, was a member of the Men of Letters. The secret society collected information on all things supernatural and used it to help assist a select group of Hunters.

The episode ended with Sam and Dean in possession of a key to that secret treasure trove of information, and in the next new episode, “Everybody Hates Hitler,” they find it.

In this new clip, Sam and Dean discover a brand new home base (to replace Rufus’ cabin). The technology might be pretty old, but there seem to be a whole lot of secrets in store for them.

Are you excited for Supernatural to finally have a Batcave? Will this new home base stack up against Bobby’s house, the Roadhouse, Garth’s houseboat or Rufus’ cabin?

Find out when Supernatural airs Wednesday at 9pm on the CW.
