When Aang wakes up, he finds himself in the Spirit World.
It's not the first time he's been here, and he doubts it will be the last. For some reason, though, this time feels different. It's like he's not whole, not real. He can't go back.
His head hurts. He wonders why he's here. More importantly, he wonders where the others are. Where is Toph? Or Sokka? Or hell—Katara?
He wonders what is happening to him.
He wonders why his spirit has separated itself from his body.
He wonders why he can't return.
So he wanders, lost in purgatory, and terrifyingly alone.
A/N: This is what you get for letting me play with mythology. A million and one thanks to heliumlost, who I bothered endlessly about this.
