Radislav Rodjanovich (1602 MG - 1679 MG) was a vestnik of the Matriarchate of Periaslavl. He worked alongside Mikhail Stepanovich to defend the border of the Periaslavl from attacks by raiders from the Kreisens. Mikhail greatly respected him.
From the Books: "I can only think of one other vestniki I have admired more, and that is Radislav Rodjanovich. I believe if I had worked with you for all your life, I would have admired you more than even he.
- Mikhail Stepanovich" - IAAWT, p. 88
