The Architect Sepulcher

There is a hidden manuscript written by an old Realm Shaper that tells of a tomb somewhere in the shadow realm containing the ancient bodies of Dèvone, Crisstio, Gavnia, and Matarius. The author of the manuscript is unknown and is said that he/she found the Architect Sepulcher and gained power or knowledge that not even Brentacaus wouldn’t understand. Many mortals and god like beings wonder how the Architects died, questions also arise that if they’re not dead why are they resting or hiding, what is their physical form, why is the Realm Shaper missing and/or why hasn't he/she returned, mysteries that only the Realm Shaper and the Architects know. The manuscript is said to not have a corporeal form and some have found it’s hundreds of scattered pieces hidden in the Realmic Flesh itself but cannot be read and disappear back into the Flesh as if not there at all.
