past
Centuries ago, his name was Franz Oelte. He was the son of the major of Lübeck, who was killed by the people from Lübeck when Franz was a child. He seeked for revenge and studied, with the help of the black abbot, black magic. When he tried to conquer Lübeck the first time, he was stopped by a good witch called Hedda, who's the aunt of the protagonists, the so-called Wächter, and helped them during the first season as a ghost. Franz, who called himself Zanrelot already, was banished to the underworld where he became the master.

Season 1
In the first season, Zanrelot tried more than once to conquer Lübeck. His finally try was to become one with a younger version of himself to become almighty. He didn't succeed because the Wächter told Franz that revenge wouldn't change everything, so he refused. Zanrelot destroyed him and thus, himself.

Season 2
In the 2nd season, he returned thanks to his apprentice Matreus who's called "son" by Zanrelot, and tried repeatedly to conquer Lübeck. At the end, he seeked for more: the "Tor zur Welt" that can make everyone who goes through it to world's ruler. When he merged with his son Jona, who helped the Wächter, Jona could get him out what killed them both.

Season 3
In Season 3, he returned again thanks to Matreus. In this season, he attacked Hamburg instead of Lübeck and fought against other Wächter. Zanrelot wanted to go through the "Tor zur Welt" again. He managed to pull his son Jona to side of evil and killed his apprentice Matreus because he betrayed him. Because people who go through the "T z W" lose their magic, Zanrelot and Jona are finally frozen by the Wächter.
