Hm.
Someone forgot to do a factory reset on their cross-transceiver.
You check the video log, sorted in chronological order. It seems to be a collection of short videos, most being of interesting sights across Unova. Mistralton's airport with a plane flying high above. The dazzling lights of Nimbasa with the ferris wheel looming in the distance. There's a video of two boys chatting by the sea, too. You're quite certain the video was taken somewhere in Castelia.
The latest one is several minutes long. The image preview is almost entirely black: you can make out a faint blob of light in the middle, but that's the most you can see. Curiosity gets the best of you.
You open it. You can see a boy shrouded in darkness. He takes a shallow breath.
Hello. My name is Nate. If you've found this video log... suffice to say I'm almost certainly dead. Best case scenario I'm barely alive, if you found me not much after I started recording.
It's been five hours as of now. Five hours stuck inside a sarcophagus, sealed shut, no air moving in or out. I let my guard down and was sealed inside of some strange Pokémon I've never seen before.
Why did I try to explore Relic Castle? Why did I risk my life to see some ancient ruins? I... I don't know. I did a stupid thing like most kids my age, made stupid choices, and now I have to die because of it. I didn't want it to be this way, I really didn't.
He looks at something near the camera. You can see his expression shift to horror.
My fingers. I can't feel my fingers. I'm... I'm going numb...
His breaths, already few and far between, sound even less frequent, even more shallow. You want to look away. You feel as though you can't. You have footage of someone, an actual person, dying before your very eyes, and your morbid curiosity refuses to let you stop here.
Please... if you find me, tell Hugh, tell Mom... tell them I'm so very sorry.
He begins to smile. Perhaps he's trying to laugh at his own misery, or maybe it's just the hypoxia getting to him.
The camera suddenly falls, but something stops it from hitting the ground. The realization hits you.
His arm's gone limp. Whoever this person was, you found the exact moment of their death.
The camera peers into pitch blackness for the next 7 minutes. There is no light, no sound, no motion, absolutely nothing. Just the knowledge that there's a dead man in the shadows.
The video ends there.
