Seeing Myne in such an unstable emotional state, no matter how Fenrir tried to ignore it, reminded herself that death is an eternal truth, and everyone faces it eventually, even her. Although she lived far longer than any hume could imagine, she wouldn't dare claim she wasn't afraid of death. Before having children, perhaps she could have. But now, three little lives with her own blood depended on her. This was, undoubtedly, the scariest moment of her entire existence, filled with constant worry for their well-being.
Fenrir could confidently say she'd seen everything on this planet in her few dozen centuries of life. If there was anything that numbed her, it was surely the death of loved ones. She'd had many friends in her early years when she was young, even a family, but time stole them all. After witnessing those she loved die repeatedly, she gave up forming connections with ordinary people.
