Kyril Finn was the leader of the terrorist movement on Rutia IV, known as the Ansata, in 2366. He was a deeply committed man, devoted to his cause of political autonomy for his people from the Rutian government, even once comparing himself to Earth's George Washington. He was also seen to have religious tendancies, and he often muttered prayers for his people. Apart from his skill as a very effective terrorist, he was also a gifted artist.
His men kidnapped Doctor Beverly Crusher in order to get the Federation involved in his fight for freedom and to help his people who were suffering from a breakdown in DNA caused by their use of a dimensional shifter. Finn ordered an attack on the USS Enterprise-D. His men set an explosive on the warp core in order to destroy the starship. Geordi La Forge was able to beam it into space, but Finn's men took Captain Picard hostage as well.
