Philosopher's stone
The player must enter four different worlds through the Bequest Globe, each of which is an amalgamation of historical and fantastical elements and is named after one of the sefirot on the Kabbalistic Tree of Life. The player seeks to recover four lost artifacts: the Rod of Osiris, the Holy Grail, the Philosopher's stone, and the Ark of the Covenant. According to Horse, "The relics you're searching for are not what you think they are". The first world, Binah, includes aspects of Arthurian legend, including Morgan le Fay and the Knights Templar, as well as Stonehenge. The second, Chesed, features Aztec ruins and a submarine interior. The third, Din, centers around an underground transit system, a steampunk carnival, and a mechanical maze. The final world, Chokhmah, takes place outside Area 51.
