Night of Wallachia (ワラキアの夜, Warakia no Yoru), originally Zepia Eltnam Oberon (ズェピア・エルトナム・オベローン, Zuepia Erutonamu Oberōn), is the thirteenth Dead Apostle and the ancestor of Sion Eltnam Atlasia. Zepia was a great alchemist, but he ultimately drove himself insane through his predictions, realizing that there was no future in which humanity would not be exterminated, and sought to oppose this law. To this end, he became a Dead Apostle, and through a deal with Altrouge Brunestud and the Crimson Moon, he was transformed into TATARI (タタリ, TATARI), a living phenomenon. In this form, he would appear in pre-calculated areas, given shape and power by the rumors and fears within the community, until the Crimson Moon would finally reappear and return him to his original form.
