For example: Is older then recorded history according to his lore. and are from ancient Shurima. turned Shurima into the dessert it is now. Is millennia's old but was trapped in true ice... by someone. trapped Gnar in ice to pre sever him to fight the watcher whom may or may not be

anyway please show your support if you are like me and are curious about this kind of stuff.
