Popularized by the Vadakendanic Procession, a Sepulchre is a vault in which a Divinorium is entombed. Their sizes range from tens to hundreds of feet, depending on their placement and the status of the Monolith before their death.
They are hollow, with a chamber from which the Divinorium generates and exhales meta. To protect the Divinorium, they are full of traps, dangers, and wards to prevent pillaging. Some are well-guarded, as well.
