This is the original protoss homeworld, Aiur. The Xel'Naga found tribes of excellent hunters that used their minds to
create a "psi blade". The planet was a hostile place, full of desert storms, volcanic activities and hostile creatures, raging
from tiny herbivores to enormous, meat devouring carnivores. The protoss had a really rough time surviving. The Xel'Naga took
them under their wing, because they wanted to create a race with "the purity of form", they wanted a PERFECT race.
