Shallot, the newly named artifact spirit, was happy.
She felt a surge of joy knowing that the prophesied one had been hiding in this seemingly insignificant world, honing his skills and avoiding immediate danger from his enemies.
She also took joy in the fact that Eren had no bond with any other Elder Seed Artifact, making her the first of her kind that he had discovered. She knew that her destiny was to vanish from the world of Anfang, as the immortal magic bound to her was unable to find a worthy successor after Shallot's passing. So, she was overjoyed that Eren had claimed her before that eventuality. Meeting him was a momentous occasion she wouldn't have wanted to miss.
