Florina is a Pegasus Knight-in-training from Ilia. One time when she was in Sacae, she fell off her pegasus and landed in a tree. She was found by Lyn caught in the tree when she was being attacked by a swarm of bees. Lyn helped her down, and the two became fast friends.
In Lyn's Story, Florina begins a search for Lyn after she learns about her departure for Caelin. She accidentally lands Huey on Migal, the leader of a band of Ganelon Bandits. They are about to capture her when Lyn and her party rescue her. She joins up with Lyn and goes with her to Caelin. After Lundgren's defeat, Florina is made a knight of Caelin.
In Eliwood's Story, Florina joins the army alongside Lyn when Eliwood aids them in retaking Caelin. In her default ending, she returns to Ilia and becomes a full-fledged Pegasus Knight. Her alternate endings include retiring to the Sacaen plains with Lyn or marrying Hector and living with him in Ostia, which would make her the mother of Lilina.
