After a few more hits -that only succeed in making his hand hurt- Kellen decides to give magic a try anyway. His magic isn’t particularly strong and he might need it soon for something less… outside of his capabilities, but he’d just been walking home until a few minutes ago and now he’s in a weird corridor so he feels like it’s justified if he isn’t thinking straight. Shaking away the extra doubts, he takes a deep breath, trying to calm down his racing heart while also using it to connect to his magic. At least that’s an advantage of being air-inclined, one’s usually surrounded by their element. It would be pretty hard for him to connect with fire or earth in this strange place where the light doesn’t seem to come from a sun and the floor is just as artificial as the walls.

Once he can feel his magic itching under his skin, ready to burst out, he crouches down. With a small nod to himself, he exhales and jumps. He lets out his magic, a strong gust of wind pushing him further up. Still, the walls around him are absurdly tall and he can't even glimpse over them before falling back down. Luckily, he does have enough power left to slow himself down and soften the landing, although it drains his reserves. He doesn't know if the atmospheric magic here will work for him to recharge with but it's not like he can go back in time to change his actions anyway. 

So, with his thoughts still racing, trying to find a way out and back home, he sits down on the floor. He rests his back against the wall and closes his eyes. Magic exhaustion feels, well, exhausting. It's not particularly surprising then that he manages to doze off despite his unease.

When he wakes up, he's confused for a brief moment. His bedroom's walls are white, but it's much brighter here than they'd be and he's certainly not lying on his bed. Soon his memories catch up with him and, unfortunately, everything that happened earlier wasn't a dream. He's still in this bizarre place, the way back is still gone and he's still upset about it, but he also remembers that none of what he'd tried earlier worked in getting him out. 

It takes Kellen a little bit longer than he'd like to admit but he manages to calm down his racing thoughts enough to decide what to do next. It's not like he really has much of a choice: he can either stay where he is and hope the passage reopens or he can follow the path and see if it leads anywhere. The white walls continue, that much he can see, and the path turns left in a right angle not too far ahead. It reminds him of a maze. 

A while of walking confirms that feeling. This place isn’t designed to be easy to navigate. If anything, its moving pathways, all indistinguishably white and too-perfect, are made to confuse anyone within them. It’s also huge, not only are the walls tall, which he’s more than confirmed by trying to jump above them and failing, whenever there’s a bifurcation he can see that they’re also wide. More than just a maze, like he could find in a park or a fair, it now feels like a labyrinth of myth. Of course, that then makes him worry about possible monsters.

Even he can’t remain anxious about it for long though, since the corridors remain empty, blank and boring. He would usually appreciate the monotony but he keeps expecting something to show up and startle him. After all, if he accidentally walked in here, other creatures might also stumble in. However, whether it’s because of the labyrinth’s size or because he’s truly alone, after multiple hours of walking he still hasn’t seen anyone (or anything) else.

At around the same time he decides that monsters (or anything interesting) are really unlikely to show up, he also notices a few other things. The first one is how the sky has remained the same pale blue the whole time. That, combined with him not feeling hungry or tired yet despite all the walking, makes him think time isn’t working as normal here. Time magic shouldn’t be able to exist but… neither should  this whole place, so that’s not a very strong argument against it. 
………..……………………………………

Although he can no longer trust that he can tell time in this place, it feels like it’s been weeks by the time something changes. He’s been walking, sitting, sleeping and raging at this place but it’s nothing he does that’s the cause. He simply walks around a corner and freezes in place at the sight.

 There’s a door in front of him. Well,  “door” isn’t quite the right word, it’s just a large part of the wall that’s missing. And instead of another corridor and more endless white walls, it leads… outside. 

He hesitates, afraid that he might be imagining it. After blinking and shaking his head, when the image persists, he takes a deep breath and steps closer to it. He doesn’t recognise the view outside and, although there’s nothing about the sight that makes it clear, he’s almost certain that it’s not in his world. 

That makes him doubt what the right choice is. Still, there’ll likely be other people, other places, perhaps even other magic, wherever he ends up. And if all of that exists, a way back home might too. It feels more likely than this Labyrinth showing him another door there. 
And, although he doesn’t examine the thought, a part of him is curious and even excited, as he gathers his courages and takes that last step out and into a new world, this time as his choice.
