Nemesis split her immense powers due to a profound realization of a grave error she had made, which ultimately led to her self-destruction.
Initially, Nemesis was overwhelmed by intense loneliness. To combat this solitude, she sought to create life. Her creations included powerful and malevolent beings, most notably Mephisto and other demons.
However, after bringing these entities into existence, Nemesis recognized the catastrophic mistake inherent in her creations. This deep understanding of her error prompted her to undergo a process of self-destruction. As a direct consequence of this act, her singular, vast cosmic power was shattered and dispersed, giving rise to the seven distinct Infinity Stones. Each stone embodies a facet of her original being and power.
This pivotal event in cosmic history ensured that her immense, singular power could no longer be wielded as a whole, preventing further catastrophic errors of creation and shaping the fundamental forces of the universe as we know them.
