Because, without a detailed look at things, Frank will not be happy:
Zavulon, a charactor from the Russian movie, Night Watch: Night Watch (Russian: Ðочной дозор, Nochnoy Dozor) is a fantasy novel by a popular Russian writer Sergei Lukyanenko published in 1998 (1st ed ISBN 5-237-01511-5).
The story revolves around a confrontation between two opposing supernatural groups (known as "Others"): the Night Watch, an organization dedicated to policing the actions of the Dark Others—and the Day Watch, which polices the actions of the Light Others.
The novel is first in a tetralogy that continues with Day Watch (Dnevnoy Dozor, Дневной дозор), Twilight Watch (Sumerechny Dozor, Сумеречный дозор) and Final Watch (Posledniy Dozor, ПоÑледний дозор).

Zavulon
(Also spelled Zabulon) (Grand Dark Mage) - An ancient schemer about the same age as Geser. He runs the Day Watch in Moscow and his plans frequently involve misdirection and hidden agendas. His power seems to rival that of Geser but he is often, if not overpowered by Geser, outwitted by him. His true form has taken on demonic characteristics because he has spent a great deal of time in the Twilight. His chosen human appearance is often misleading, as he appears as a thin intellectual who does not seem to be a threat to those who do not know him. Day Watch Novel: Geser's consistent ability to outwit him eventually forces the outside forces of the gloom to step in and restore the balance between Light and Dark. Face of the Dark Palmira: His human name is revealed to be Arthur.
