Kalista's inspiration?

Has anyone here ever played the playstation 2 game Primal? In the game there is a world with a race called the "Wraiths" and Kalista is very reminiscent of them. In the game, the wraiths bend time to move very fast moving around in what appears like mist, much like Kalista's dash. They are also very thin and have the same sort of body shape of Kalista, as well as very unique weapons, including a spear on the wraith guards in the game called "Valkyries". The blood moon skin looks especially like this picture I found of them! :D Wonder what your guys thoughts on this are, or if anyone from riot can confirm this?

The Wraiths are also set in an aristocratic, french revolution, christian symbolical world which matches the theme of Kalista and the 7 deadly sins. (I.e. the mist on 7 different champions representing a different sin, Twisted Fate - Greed; Hecarim - Wrath; Leblanc - Pride; Lissandra - Sloth; Cassiopeia - Lust; Xerath - Gluttony; Zed - Envy) Edit: I also included Blood Moon Kalista's splash art. They're like identical!!
