Night of Wallachia (ワラキアの夜, Warakia no Yoru?), originally known as Zepia Eltnam Oberon (ズェピア・エルトナム・オベローン, Zuepia Erutonamu Oberōn?), is the thirteenth of The Twenty-seven Dead Apostle Ancestors and the ancestor of Sion Eltnam Atlasia. He is very different from other Dead Apostles, as he can not actually be said to currently exist.[1][2] His nature is that of a phenomenon known as TATARI (タタリ, TATARI?), derived from a Japanese word meaning "curse", a recurring event that grants physical shape to the fears and rumors that circulate within a community. This phenomenon first manifested as the image of the vampire that was falsely believed to haunt the province of Wallachia in Romania, Vlad the Impaler, thus granting him his title. He is the main villain of Melty Blood and his Reality Marble TATARI is central to the Melty Blood series.
