Recently played Wolfenstein New order and their use of Kaballah (renamed into Da'at Yuchid) background of Nazi power remided me of old-old RP compaign I led as GM and also used similar line as distant (50 year ago) past for it's storyline, with assumption that origin of occult knowledge and laylines power came from beyond Earth's boundaries.

Sketch of my original character, later - my fursona Miyu Guardian (Hogosha),who had position\duty of a Da'at Somr - Sentinel of Knowledge (hebrew), also known as Guardian at Gate and Engineer of in that world.

Hilt of sword supposed to be decorated with enchanted gems, laid in form of Sephirot diagram with main power gem in Da'at node (the middle one, which links all of them). 10 swords like that existed, for each Sephirah, except Malkhut - that incrustation was made at seat of throne, in castle, the Citadel that guarded Gate between Worlds.
