Quest List
Night falls. Red lights flicker through a curtain of rain, carrying the damp, metallic smell of iron and dirt.
Rhythmic Trembling Sound:
Creak— THUMP—
Rhythmic Trembling Sound:
Creak— THUMP— Creak—
???:
Rainy night conditions detected. Condition… matched.
???:
Mis…sion—initiated.
???:
Do not… interfere.
A strange male voice grates through the air, raspy and spooky like a blade scraping glass.
You turn around to lay eyes on a Route Constructor. Its exterior is weathered, and its serial number is barely recognizable. Looks like it hasn't been in service for a long time.
Route Constructor (Strange Male Voice):
Mis…sion—initiated.
Route Constructor (Strange Male Voice):
Do not… interfere.
You try to shut down the Route Constructor, but find it has no power source. It isn't connected to any grid.
There's no way to shut it down. Its red lights pulse faster as the road stretches outward, a suspended pathway hovering in the air, looking ready to collapse at any second.
Rover:
(An unexplainable phenomenon, or an urban legend…? Is this why Mayo wanted me here? I should call her.)
Mayo:
Eh? Rover is calling me first? Don't tell me... you're finally ready to join the club, huh?
Mayo:
Wait, the rain is really loud. You're outside… Are you in the Collapsed Ravine right now?
Rover:
Yeah. Rainy night. The Collapsed Ravine. A Route Constructor spouting creepy lines. And...
Mayo:
...A road suspended in midair looking like it might fall any second.
Mayo:
Of course! Don't underestimate my "database," hehe!
Mayo:
Let me put it this way, if it's an unexplained story or a paranormal rumor in Lahai-Roi—firsthand, witnessed, or just gossip—it's in my files.
Mayo:
Let me think… Right! The first report came from a Voidmatters student. She said that on rainy nights, one of those printing Constructors appears in the Etching Plains and starts building a road...
Mayo:
No deployment record matches it. No team claims it. A Route Constructor that appears out of nowhere, like a ghost tied to rainy nights.
Mayo:
She even got a video. Caused a huge stir. Some called it a hoax, others said it was a cover-up for a cursed zone...
Mayo:
Then poof! The video vanished. Wiped clean. The whole discussion just... died.
Mayo:
Hmph, she had so much potential... Why didn't I recruit her?! A missed opportunity... Wait, I'm getting off track!
Mayo:
Rover, look around. Besides the road, is there anything else you can see...?
Her voice is swallowed by a sudden crack of thunder. A flash of lightning pierces the rain. A shadow darts past, flickering in and out of view.
On the floating road, a riderless motorcycle glides like a phantom, its engine rumbling low.
Mayo:
That was the big debate.
Mayo:
Some think the bike is a coincidence. Others say it's part of the urban legend and that you should stay far away. Unlike the road, it moves. It could charge right at you.
Mayo:
But I think the motorcycle is the key… Rover, do you trust me?
Mayo:
The motorcycle doesn't need to be here. It's an extra, an optional part of the scene.
Mayo:
And that Route Constructor keeps building the road… Doesn't it feel like it's building a racetrack just for the motorcycle?
Mayo:
So it's not just building the road. It's recreating an entire scene! A moment frozen in the rain! You know what that means, Rover!
Mayo:
Chase that motorcycle! Break the pattern and see what happens!
Mayo:
Well, I'm not sure... that's why I'm asking if you trust me!
Rover:
No way... That speed was insane. It was way too fast.
Mayo:
It's okay. You did great. You were only off by a tiny, tiny bit.
Mayo:
It is its home turf, after all. Who knows how many times it's run this route? We'll just have to try again next time!
Mayo:
—Now!
Rover:
Phew. So that's... it?
Rover:
Hold on! Is that a storage module? Did the Route Constructor just spit that out?
The trembling stops. The Route Constructor's red glow fades into a steady, calm light. When it speaks again, its voice is gentle, delivering its final announcement.
Route Constructor (Soft Male Voice):
Rainy night conditions detected. Condition matched.
Route Constructor (Soft Male Voice):
Test initiated... Failed. Test subject missing.
Route Constructor (Soft Male Voice):
Repeat: Test subject "K. Nelson" missing. Test initiation failed.
Route Constructor (Soft Male Voice):
Correcting objective—Initiate repair infrastructure. Escort K. Nelson to safety. Prevent his death.
Route Constructor (Soft Male Voice):
Mission... start... Mission... end.
The Route Constructor falls silent, as if its power has been cut for good.
Mayo:
...Rover, do you think Nelson's final test was a success in the end?
Mayo:
Was rebuilding that road every rainy night simply a glitch, just it replaying the moment Nelson died? Or... was it making its own choice, trying to undo a single, tragic regret?
Mayo:
Ugh, a conclusion you can neither prove nor disprove. Annoying... also kind of heartbreaking.
Mayo:
Huh? Didn't expect you to say that!
Mayo:
But... I still believe that souls are real. And that Route Constructor's soul? Maybe it's in the very programming K. Nelson poured his heart into.
You receive a message from an unknown sender.
{message} ???:
You're Rover, right?
{message} ???:
The forbidden stories, the unexplainable phenomena... the stuff of campus legend. Ever heard 'em?
{message} Rover:
You opened with this exact line last time.
{message} ???:
But come on, doesn't it set the mood perfectly?
{message} ???:
Alright, alright, back to business. If you're interested, you should check out the Collapsed Ravine on a rainy night.
{message} Rover:
What’s there?
{message} ???:
Obviously, it's—
{message} ???:
A secret! You'll understand once you get there.
