Allison helped her husband Nolan seize the throne of Aethelgard with her resources, and even took a poisoned arrow for him with her own body, which left her barren. But when she was ill, he took her elixir and gave it to Hollie, a rich duke's daughter who was pregnant with his child. He wanted an heir, and Hollie's family's money, so he stripped Allison of her crown. On her exile, Allison was saved by Simon, Crown Prince of the powerful Sacred Empire. It wasn't coincidence, for Simon had been searching for his long-lost sister, and that was Allison. Backed by her real family, Allison returned to deal with Nolan, and to investigate her adopted parents' death. She would let Nolan know she had more than one secret identity, each enough to crush him.
