Her bloodline had been cold for a while now, there had been no battle, hence there was no need for the fire in her bloodline. But that changed when she saw what Soverick did while overcoming the ordeal that is the mountain range. She knew at that point that he must become her rival.
Her bloodline, the eternal battle royal bloodline like most bloodlines gave her two advantages in affinity. For the elemental advantage, she got the air element. So she had a god-level talent for the wind. Then there is the advantage of her divine ability. For her, it is the affinity of battle. God-level talent in wind is not anything special nowadays when every child with a pure awakened royal bloodline has one. What's special about her bloodline is the ability to grow more talented by defeating talented people. She grows stronger with every victory by stealing their talents.
