Bella was one of the fifteen horses brought on King Lief's quest to destroy the Four Sisters. She was ridden by Barda until their company reached Forests of Silence. Lief, Barda, and Jasmine split off from their escort to evade an assassin that had been trailing the group and went through End Wood on foot. Bella and her fellow horses went with the guards and Rolf the Capricon to the town of Ringle.
That night, Rolf transformed into a false Rubydragon and slaughtered the palace guards. Bella survived the incident with two other horses, Honey and Swift. The three eventually found their way into the ownership of Laughing Jack, who used magic to transform the them of them into large black horses identical to his current horse, the former keeper of the Bone PointLighthouse, Red Han.
Bella was forced to pull Laughing Jack's wagon to the Funnel after he acquired Zerry and the Belt of Deltora for disposal. During the trip, Jack taunted the thirsty horses with a bucket of water.
Lief, Barda, Jasmine, and Steven pursued Jack to retrieve the belt. While Steven distracted him, Jasmine attempted to free the horses and recognised them through the magic. However, Jack caught onto their ploy and escaped before she could.
Bella, Honey, Swift, and Red Han pulled Jack's wagon to Ava'sShop so he could impersonate his sister and lead Lief, Barda, and Jasmine to their deaths. Jasmine was later able to trick Jack into taking a coin from his ship, The Lady Luck, and when he was taken aboard, his spell over the horses was broken.
