Cosmic Reaver Kassadin’s astral appearance is inspired by the Southern Cross, the smallest constellation in the night sky. Communities all across Oceania treat the Cross with special reverence -- from the folk tales of the Maori to the symbolism of Australian Aboriginal astronomy, the constellation holds different meanings in various Oceanic countries.
The Southern Cross features most prominently in Cosmic Reaver Kassadin's Recall animation, in which he traces the shape of the constellation after opening a rift into space. His new weapon also takes on the shape of the Cross, being outlined in stars.
