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, Zwepia 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.

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.

Night of Wallachia is the main villain of Melty Blood and his Reality Marble "TATARI" is central to the Melty Blood series.

Legal Information: He stands 180cm tall, he weighs 67kg, he is over 500 years old, his blood type is O, and his birthday is on May 30. His species is classified as both Dead Apostle and Magus. He is of the Eltnam bloodline, and his descendents are Sion Eltnam Atlasia and Sialim Eltnam Re-Atlasia.

Apperance: Even though his apperance can take on anything, he usually bears blond, somewhat spiky hair, he bears a dark brown cape with red outlines, held together around his neck hy a small rope. He wears a posh dress akin to standard Atlas attire, it is dark purple with orange ingravings. He wears a white undershirt which sticks out through his neck and his sleeves. His skin is fair, almost pale, like white bed sheets.

Personality: Zepia went mad after he found that, no matter how much he searched, that there was no way for humanity to avoid its destruction. His greatest wish became to create a future even he cannot predict. In his madness, he has accepted that the end of the world, following a desperate struggle to live on, is not true destruction but instead a conclusion. He does see some form of hope in Sion's endeavors, and wishes to see her answer to the problem.

He has taken to equating his role as TATARI to that of a director putting on a play. He frequently refers to different "acts", the "stage", and the "audience" when describing his massacres. He likes to put on theatrical speeches while conversing with others. While he generally displays a calm and stoic demeanor, he is prone to go into fits of ranting insanity where he shows blood red eyes that leak blood just from being open. He has lost himself in his madness, but has embraced it at the same time, having decided to enjoy the end of the world at his leisure.

He likes to play around with his manifestations, and he greatly prefers female bodies to those of males because he thinks drinking blood in a woman's body is a necessity for the climax of the scenario. He has not had a woman's body for a long time due to being unable to choose his form. While he is fine being one of the Twenty-seven Ancestors, he would rather become an original True Ancestor, Arcueid, which would be more appropriate for his final form. He doesn't like bodies without abilities, such as Akiha Tohno, but he does enjoy her appearance.

He greatly enjoys slaughter and the ironically tragic deaths his manifestations are able to cause in some cases. He cruelly likes to mock people by exploiting their deepest flaws and fears before tearing them apart.

Background: Originally a genius Alchemist from Atlas named Zepia Eltnam Oberon, a member of the prestigious noble family of Eltnam, for whose downfall he was responsible. He had chosen the name "Oberon" for himself. In the World of Magecraft, where a resemblance of names holds a deep meaning, the relationship between him and the Fairy king Oberon of A Midsummer Night’s DreamWP is a story only he knows.

During his research, the ability of the Atlas Alchemists to calculate and predict the future eventually revealed to him that only destruction would be an absolute result for the World. Obsessed and driven mad by this realization, he sought to oppose a universal law known as Sixth Law, which was said to be the bringer of that ultimate destruction, with the intention of creating an impossible future that would escape even his calculations. Zepia became convinced that he had to become a Vampire and increase his power in order to reach The Sixth Law. To become a Vampire, he needed to break the golden rule of Atlas, that everything created in Atlas must be kept and disposed of within the domains of the organization. He left Atlas and continued his research outside, transforming himself into a Dead Apostle. In doing so, he disgraced his name, and now the Eltnam are considered a ruined noble house of Alchemists. His metamorphosis into the TATARI, theorized and formulated as part of his research of the Sixth Law, was realized through a pact with Altrouge Brunestud, who summoned the Crimson Moon and transformed him into the curse, casting him into a cycle by which he would continuously manifest in pre-calculated areas, the journey destined to finalize a thousand years later when the reappearance of the Crimson Moon would return him to his original form as Zepia Eltnam Oberon. The last anybody heard of him was 500 years ago, in Transylvania.

Main Ability: The nature of Night of Wallachia's current existence resides in his Reality Marble, TATARI, which allows the materialization of the rumors and fears of a region into physical entities. Unlike a normal Reality Marble that is an inner, differing reality from the outside world that has a constantly fixed form, TATARI is something that "takes form from nearby humans" and applies it to the surrounding area more akin to Marble Phantasm. In a place where something is feared absolutely, the power is absolute. As a type of Reality Marble, the contents of it are still separate from the world around it despite seemingly being integrated with it. Even the strongest Dead Apostle can not maintain a Reality Marble for more than a single night, so Wallachia's activity is only limited to one night after it is activated.
