Vladimir I was a distant Get of Fenris kinfolk. In 980 C.E, he won the throne of Russia with the help of the Varangians. Warders of Men appear in Kiev during this period. Vladimir converted to Christianity in 988 C.E. and quickly established Christianity in Russia which opened the way for Tzimisce, Shadow Lords, and Ventrue from Europe. The church flourished despite Garou efforts, and as Vladimir was a Get kinfolk, the Silver Fangs blamed the Get for the new church.
