Rosita Gonzalez was a sergeant in the army of the United States of Boise.
Rosita met Edain Aylward while he was competing against Boise soldiers in a display of his skill as a hunter/warrior.
She aligned herself with Frederick Thurston and he told her to remain in place in Idaho. She took letters from Mathilda Arminger to deliver, if possible, to her mother. She successfully delivered those letters to Tiphaine d'Ath.
Rosita was wounded in one arm during the Battle of Pendleton.
