The Ebon Mountain is a location from The Legend of Zelda: Breath of the Wild. It is located in the East Necluda region of Hyrule. Atop the peak lies a small pond in the shape of a broken heart, not to be mistaken for Lover's Pond on Tuft Mountain. Fairies are occasionally found flying above the water near Mimos, who thinks that the pond is the actual Lover's Pond.
Judging by the ponds shape, it is possible that it has the opposite effect of the one on Tuft Mountain.
