Owner of the Crypt

Who is the owner of the Crypt of Resting Thoughts? Is it the Ahib chosen by the queen who claimed the Thornflower Throne? The Dwarven slaves who the Ahib call barbarians? The first Fallen Ones, who are beneath this crypt and cannot escape, who are unable to die and will cry out forever in the Abyss of Oblivion? Or is it the phantoms of the ancient people of Orzeca who were unjustly sacrificed and bound by ancient darkness? - Excerpt about the Crypt of Resting Thoughts from the writings of a Dwarf long gone
