Attack?
Living in the mountains meant two things: one, is to develop good instincts, and two, is to know how to survive arctic winters. Faustina learned them not in training, like those in the epic stories of heroes and sagas with protagonists training under masters how to sharpen their senses. Faustina found such stories engrossing, and she dwelt on their worlds—unaware she was also similar to the protagonists in some way.
Faustina grew up on a secluded mountain above Nebel, the village under the mountain which Eula deemed to be infamous. The mountain was a dangerous place to live in; its forest was ridden with bears and beasts of several sorts, its hedges were also bombarded with poisonous plants in the guise of delicious berries. The mountain, however, served as Faustina's safe haven for several years. She was a Heilen, after all—the isolation was a blessing.
