Dark mountain creatures (Lunari champions)

With the Mount Targon lore on League and the announcement of Aurelion Sol we can imagine that it is a dragon from Mount Targon related to the sun (probably the "winged and horned boy" from Leona's story). But that same story also mentioned dark creatures of the mountain that decend with the mists. I think it would be sweet to eventually get one of these creatures as a champion. Maybe they would be related to Diana's faith and the Lunari. I just think its a cool opportunity and I hope that is a plan for the future.

Edit: I wrote this before reading Diana's story. I think the possibility of seeing the monsters they describe in her story as a champion would also be sweet. Though their description might mean that they are also void creatures. I am unsure.
