So, basically Aur'Rax is a creature from the Void. He came to this world in search of prey to satisfy his growing hunger.
Now, moving to the champion's Hunger mechanic. The Hunger mechanic works in the way that Aur'Rax starts with 100 Hunger, and he loses 1 Hunger every 1.5 seconds. When the hunger bar is below 10, Aur'Rax's abilities gain a bonus (Also, Aur'Rax's abilities have no cost related to them). When the hunger bar reaches zero, Aur'Rax loses 2% of his maximum health per second. Additional info can be seen in his Passive 'Endless Hunger'.
Aur'Rax, Predator of the Void is a custom champion created by Marko Mijovski.
"They won't notice me."
"I see you."
"I'll be there."
"I grow hungry."
"Slice them in pieces."
"I see you!"
"Consume them all."
"I can smell you.. (Aur'Rax sniffs*). Ugh, you should really take a bath!"
"I was hoping for a raw yordle, but this will do."
"I will swallow you whole!"
