Why was Sheikah banished?
Correspondingly, are Sheikah Hylians?
The Sheikah are a humanoid race, bearing great resemblance to Hylians in both appearance and magical capacity. The Sheikah, however, are known for their distinctive red eyes and pointed ears, which they share the latter with the Hylians.
Simply so, what does the Sheikah eye mean?
The Sheikah symbol is an eye with three triangles above it and a big tear. The meaning of this symbol is rather confusing, although it can be interpreted that the eye is a symbol of truth, a noun many times asociated to the shadow folk. The three triangles may symbolize the sacred Triforce, that they protect.
The Sheikah Monks are a group of monks devoted to the Goddess Hylia they lived 10000 years before Breath of the wild and are only seen in the form of mummies still inhabited by the soul of their respective monk. They are the ones who built the Shrines in the name of the Goddess Hylia.
