Dust of Osiris is a potential future version of Sion Eltnam Atlasia created by Wallachia from remnants of her soul. She is known as the 13th of the 27 Ancestors of Dead Apostles. She has no ego nor emotions and behaves more like computer, always busy with calculations and recalculations. Dust of Osiris tries to recreate the "Hologram Summer" from the previous year, destroy the future and keep an eternal record, as she believes there is no future for the mankind anyway.
