Correspondances is a 193 pages book, apparently limited to a run of twenty-five, published in Porrentruy in 771 AT by Roman De Malegarde.
This work, the existence of which is undeniable, is surrounded by a deep mystery. It includes, among other things, the whole of the Testament of Mary. To this day, we know about the location of a least eight copies in the Lighted World, all of them received anonymously by people closely connected to the Obscure World.
