Galina was Dimitri's old instructor from school.
Several years ago, Galina traveled to Prague and fought against a group of Strigoi. Sadly, she was overpowered and turned into one. After Dimitri was turned into a Strigoi in the end of Shadow Kiss, he stays with Galina in her own estate, far from Novosibirsk. In Blood Promise, she allows him to keep Rose Hathaway, but demands that she is either turned or killed eventually. When Rose is trying to escape, she runs into Galina but Dimitri attacks his old instructor to save Rose. Galina overpowers him and he asks Rose to stake her, which she eventually does.
