Hebran is the common term used to refer to the native tribes within the mountain ranges of the Hebra region. It's an easy term really, given that absolutely nobody else would consider living there as the conditions are unforgiving to the average Hylian. Historically it's been known that there are two major tribes, separated by the great peak. They worship the light, cycles of the day and auroras in the sky, and have typically been unfriendly with one another given their belief their day-night cycles are 'different', as the gigantic peak blocks the sunlight for one tribe and the moonlight for the other. An average Hylian probably wouldn't realize these people exist, let alone if they understand Hylian. For the most part, they don't, and communicate with a shared collection of sounds, clicks and whistles with the Rito. Otherwise, they speak their own language. Since the Calamity however, the two tribes have converged into one, setting aside their differences to prioritise their survival. Those who do speak Hylian common have a soft, wispy accent that is spoken mostly nasally.
