Count Vortrifrani was a member of the Vor class on the planet Barrayar. He was a District Count and sat in the Council of Counts. A political foe of the liberal Emperor Gregor Vorbarra and the Progressive Party, he served as leader of the opposing Conservative Party. He was discredited when he was suspected in a treasonous plot by hyperisolationist extremists allied with him to crash a space feighter into the planetary capital of Vorbarr Sultana and kill Emperor Gregor. This was the so-called Yarrow plot.
