My idea for a Pantheon rework (v3)
(I got some feedback last time on Reddit and Boards about how the lore I made up sucks, so I'm changing that. It's a hell of a long read, but I'd appreciate if you would read all of it, so that I could get some feedback on how to better this. I honestly feel like this could be a really good rework.)
Pantheon, the Soldier of the Stars
**Lore: ** Pantheon was just a fairy tale at one point, a story passed down from generation to generation about a warrior so powerful that he could fight the gods themselves. But everybody knew that fairy tales aren't real. Pantheon couldn't exist, right?
It all began at the height of Shurima, before Renekton was turned by the evil power of Xerath. In that time, a young boy named Atreus was born. Even while he was still toddling around, he grabbed anything that he could reach and swung it around, mimicking the sword swings of the warriors that practiced near Atreus' home. As soon as he was old enough, Atreus enlisted in the Shuriman army. He got in, but it was not like he expected. He was one of the weakest boys in the army, and he soon learned that fighting with a stick is very unlike fighting with a spear. Atreus realized that he was doing badly, and asked for help from one of his instructors, Pylas, who was actually a close friend of Renekton. Pylas was a legend at the Shuriman Army training grounds. Adept at every sort of weapon, ranging from bow and arrow to a mace, it was said that he'd never lost a battle before. However, it was the spear that really made Pylas the legend that everybody in the army said he was. Renekton himself has said that watching Pylas fight with his spear is like watching a delicate but precise dancer. So, of course, Pylas trained Atreus in the art of the spear every night and day. Atreus was a quick learner, and was soon able to stand his own against Pylas. Proud of his pupil, Pylas told Atreus that if he wished to become the best warrior in the army he had to go on a spiritual journey. Physical strength is important, but mental strength is more important. Pylas told him that he had to climb Mount Gargantuan, or Mount Targon, and witness the power that may bestow him. So Atreus, determined as he was to be the best, went on the trek up the side of the gigantic mountain.
It took Atreus many nights to reach the tip of the mountain, and during the time, he began to feel the effects of frostbite. But he wished to gain the ultimate power that his master Pylas told him of. However, once Atreus got to the top of the mountain he found... Nothing. Nothing except rocks and the Nevermelt snow. Atreus felt betrayed by his master. Had Pylas lied to him? Was Pylas jealous of Atreus, and wanted him out of the army so Pylas was still the best? With those thoughts in his head, Atreus succumbed to the frostbite, and died. Except he didn't really die. He just thought that he did. He was just able to see all the spirits of the Mountain. All the aspects, and their prized possession, Aurelion Sol. Atreus looked up at all of the aspects, and fainted.
The aspects took Atreus' spirit back to their world, the world of the Mountain, or True Targon. All the aspects live there, as well as the disgraced Demacians sentenced to the Crown of Stone. When Atreus finally woke up, the Aspect of War was waiting for him at his bed. The Aspect of War came up with an arrangement with Atreus. Atreus would become the Aspect of War's avatar, but not permanently. Atreus would be in control any time except for in battle, and then the Aspect of War would use his fighting skills to help Atreus. Atreus wholeheartedly accepted, and was christened Pantheon.
When Atreus returned to Shurima, he discovered that he had been resting in True Targon for centuries. Shurima was in ruins. It had fallen. Since that day Pantheon has been fighting for Shurima and for it's return.
Although the stories of Pantheon have changed a bit over the past few millennia, the same character still stands at the heart of it: the mythical Pantheon, the Soldier of the Stars.
