Ravaged by Rune Wars long past, the lands south of the Great Barrier are wrecked by chaotic magical storms, leaving the grasp of nature's rule tenuous at best. While abnormal flora or fauna are the norm rather than the exception in these ruined areas, perhaps none is more curious than the case of Rammus. While no one is entirely certain why an armadillo from the Shurima Desert crossed the Kumungu Jungle into the Plague Jungles, Rammus made just such a journey. There, amongst the twisted vines and festering rot, he came across an oddity - a healthy evergreen hedge maze, stretching as far as the eye could see. As he explored the maze, something compelled him towards its center - a light, a presence of some kind. As he drew closer, the light surged, blinding him and knocking him unconscious.
When he awoke, Rammus' whole world had changed. The maze had vanished and he felt truly cognizant for the first time in his otherwise unremarkable life. As his predicament dawned on him, Rammus had a moment of panic. As he trembled, the earth around him began to shake, the intensity increasing until he managed to steady himself. As the quake receded, Rammus arose and left the Plague Jungles in search of others like him. His search brought him across all the lands south of the Great Barrier, but everywhere he went, he was unique. The hardships of this sojourn inspired him to craft the suit of armor that would earn him the title of Armordillo. Rammus's quest eventually drew him to the only place where a sentient armadillo is less than confounding - the League of Legends.
"I've seen a lot of things, but this... this is a first." - Ezreal, the Prodigal Explorer, after first meeting Rammus.
