The Binyan is the codename for the Holy Tongue Society's hidden “knowledge base” in ‘Ir Reshumim. It is located where the Shrine of the Book once stood in what used to be called Jerusalem, and it houses the Society’s prized possession: the War Scrolls.
The Binyan’s exterior symbolizes the apocalyptic battle to come between the Sons of Light (represented by the white dome) and the Sons of Darkness (represented by the black wall).
The Binyan is based on the בון shoresh root.
The Binyan in ‘Milhamah’ comic
In Update #1, Tiqwah Tawit stands outside the Binyan and recovers a damaged speech balloon, which she takes to Shem 'Etzem. Shem travels further underground in the Binyan to grab another treasure, the Dalet foundation glyph. But that’s when the Bavel Macrostructure henchman Deli opens a Bavel gate portal and invades the base.
