The warrior walked through the forest, dappled sunlight and shadows cross his path as he continues his forward march. He travels alone, no monsters or even the odd travellers cross his path. "The same but different." He walks on, only the bird song and the sound of the warrior's footsteps disturbed the quiet of the forest. He arrives in a clearing and looks up at the sky, shading his eyes as he did. He then reached into a hidden pocket, and brings out an object he had not shown to any one, a large blue crystal. The light reflected off its surface as the warrior looked at it fondly, as if it meant the world to him. And in some way it did, it was the only thing he had of the adventure with his companions as the Warriors of Cosmos. He remembered the Goddess they had been summoned by, her gentle and calming light, her kind voice and her unwavering trust in her Warriors. Now, each of her warriors held a piece of her light in form of a crystal. Remembering his Goddess brought on the memories of his companions:
The strong young man, a jack of all trades, whose seemingly small dream grew into a dream shared by them all.
The young boy, with the heart of a much larger warrior, who tried to show he deserved to be there as much as the others.
The young man, who could control both light and darkness, whose kind and strong heart was a source of common sense among the warriors.
The free-spirited young man, the light hearted and seemingly trouble free young man with the unique ability to copy their own abilities.
The powerful but kind hearted young woman who feared her powers but fought to the end for a dream and hope.
The silent man with a sword the same height as himself, who only wanted to find his reason to fight despite the interference of another.
The young man with the scarred face, who was like a lion, proud and protective of his pack as he fought against the manikins.
The young man with a tail, the thief with a heart of gold, who could reach places the others couldn't but was as free-spirited as his friend.
And the young man, whose feelings towards his father confused him, but his cheerful personality and helpful disposition made him a strong warrior.
He let himself get lost in memories of their struggle together but it was bittersweet. He would never again see those warriors again, having all returned to their own worlds. And that does not even include the warriors from the cycles before them who did not make it to the 13th cycle. But those memories were forever lost to him, as it was to the others. But, at least his memories of this cycle had not been lost, so he could remember them. And maybe he would see them again, either if he came across a portal to one of their worlds or, if it existed, the life after this because, if anything he knew he'd see them again. They were connected after all, and not even the death of their Goddess had stopped them after all so this was just another roadblock after all.
Their adventure only remembered in history, by what legends could tell. 3 of the warriors remained in Corneria but the last, the Warrior of Light became restless and left these lands. Where he left to is unknown but they knew he was searching for something. Whether he found it, they don't know but stories of a horned armoured knight who travelled across distant lands reached them even if they never saw him again.
A/N
This is only my interpretation of what I think goes on in the head of the Warrior of Light so take it with a grain of salt. I felt he was always somewhat spiritual, not believing in coincidences and that everything has a meaning with all his speeches that he gives in the game. He also doesn't do anything lightly when making decisions like in 012 where he decides with Kain to send some of them onwards. But I also feels he needs a goal to work towards, whether it be fighting Chaos or protecting Cosmos but he feels lost without such a thing. He would probably leave Corneria sooner or later to try and find some goal to work towards. I also interpret how he sees the other Warriors of Cosmos from his disconnected point of view so it's not particularly in depth of any of them.
