Pfrizzek was a Lyran senior commodore and the commanding officer of Starbase 47. (RIS Bouteina)

He was promoted from commodore to senior commodore after the Lyran Democrative Republic signed the Treaty of Bajor, even if he fought only one of the three engagements of the LDR during the Dominion War. (RIS Bouteina: "Yesterday's Lyrans")

The main highlight of his life was the first contact he made with the Borg, during the Battle of Krypton. However, shortly after the battle at the Grave of Thoughts, he lost his first wife in battle.

He became the Count of the Iron Fang County by 2401. (Star Trek: The Stoneship Files: "Highly Illogical")
