How much common knowledge is the existance of the vastayah?
I know in Ionia they could be considered pretty much common knowledge, but then there is the kiilash in Shurima, and the drawings of minotaurs working in forges in the Medarda Heirloom map. But even with that, people in Piltover doesn't seem to have any knowledge of their existance if Eduard Santangelo diary serves as reference. So, how many regions have common knowledge of their existance? How widespread is vastayan population in areas like Noxus, for example?
