Demestriu was born Fyodor, brother to King Stefanovich. He recruited his nephew Lothaire to kill immortals, harvest their powers and memories. He freed Lothaire from being buried alive to secure the Horde crown for himself. When crowned by the Horde, he took the name Demestriu, which meant rule without end.
