Nayru
Nayru is one of the three creator goddesses of Hyrule, and arguably Termina. She, along with her sisters Din and Farore formed the world of Zelda out of chaos, each providing their part in the process. Upon departure, they left the triforce, the essence of their power, in the sacred realm.
Nayru, the Goddess of Wisdom, filled the terrain that her sister Din created. She is the master of water magic, and the spell Nayru's Love is (obviously) named after her.
Nayru, the Oracle of Ages is named after her.
