Fionuir Iktomi Doyle is the son of an Irish-American Marine and the Grand-Daughter of a Lakota Sioux Medicine man. After the death of his father in the Beirut bombing, Fionuir's mother returned to the Cheyenne River Indian Reservation to live with his Great Grandfather, Iktomi Walking Bear.
Iktomi, born at the end of the Great Indian Wars, was a wise Medicine Man as well as a proud Lakota Warrior. Realizing Fionuir has a strong mystical link with the spirit world, Iktomi decides to train him in the old ways of the Lakota warrior.
As a US Navy SEAL, Fionuir and his team were sent to Afghanistan. Then while on leave, he flies to Italy to meet with his wife and newborn son. However, upon his arrival, he learns they were brutally murdered in a recent terrorist attack. This horrific act became the core of Fionuir's personal war on the organization known as the Islamic Brotherhood. Using his Special Forces training and that of a Lakota Warrior, Fionuir began his hunt for those responsible for the death of his family, and to settle a blood debt owed.
