PBE Skin References

I was thinking, when the new skins came on PBE I decided to think of neat references for each of them:

Gravelord Azir - possibly the Lich King from Warcraft Lionheart Braum - most likely the Knights of the Round Table Caskbreaker Gragas - the armor is possibly a reference to Solaire of Astora from Dark Souls Elderwood Hecarim - probably Cenarius from Warcraft Classic Illaoi - maybe a reference to the movie Atlantis: The Lost Empire Void Bringer Illaoi - Kerrigan from Starcraft? Dragon Trainer Tristana - obviously a reference to How to Train Your Dragon Kappa Whitebeard Ryze - generic fantasy mage like Merlyn Swiftbolt Varus- honestly I have no idea

Let me know what you guys think, you can help me with the Varus skin because i have no clue on any possible references for it
