They set down on its back, and the dragon slowly starts to swim away the opposite way they were originally going. There appears to be a tiny sliver of land that way though, and the key seems to agree, as the piece spins around to point towards the small sight of land
(Oh fair warning I've got dinner in a few minutes)
"Well, that's handy. Any ideas when we get there?"
Mike nods. "If it's safe, you'll stay with the chopper while I go find some info."
"You don't want my help?"
"Nah, I got this. Thanks."
"All right."
Lighthouse starts to flash again. "I wou-wouldn't do that I-I-if I were you. The l-labs are of-f-f lim-mits to civilians and vis-sitors. It is s-safest to c-come with me."
"Oh, whoops. Forgot to turn the radio off." Mike sighs. "Thanks, buddy. Lead the way."
They swim for what seems like hours until they finally see land. There's a sheer cliff face, and lights can be seen from on top of the cliffs. As they get closer, green-blue lights start to flash in sequence along where the cliffs meet the water. Lighthouse starts to flash back
"Interesting," Mike remarks. "This seems like a dimension that would be fun to explore, if we had time."
"I agree. hopefully it's not a trap."
"Ouch, yeah. That would be annoying."
For a moment, the flashing stops. Then, both Lighthouse's lights and the ones along the coast begin to glow solid and bright. "At-t-tention passen-n-gers. I acknowledge this w-w-will sound stran-nge, but we mus-st dive to reach the har-rbor. If you wo-would kindly m-move your craft into the h-h-hangar." As the creature says this, the top portion of its head guard opens up to reveal a slightly rusted hangar
"Yeep! Okay, let's just push it in," Jacob says quickly.
They climb out and shove the chopper into the hanger, folding the rotors to keep them safe. Luckily the scales are slippery, so it's not impossible to move the heavy aircraft.
"Okay, we're ready," Mike calls, pulling Jacob back inside.
The hangar closes behind them, and lights fire up inside the hangar. An automated voice comes over a loudspeaker system. "Attention all pass-sengers. Di-dive sequence initiating in th-three, two, o-o-one…"
"Hang on, Jacob," Mike mutters.
Suddenly the hangar jolts violently. "Ap-p-pologies. It has been a wh-while since I l-last had pass-s-sengers."
Mike resists an eye-roll. "Take your time. But please don't drown us in here."
"N-No worries. Ev-ven if there was a b-b-breach, the w-water here is m-m-made of a chemi-ical that is b-b-breathable to e-e-exclusively l-land creat-t-tures."
As they continue to sink, another automated message plays over the speakers. "W-Would you like to access the t-tour screen?"
Mike tilts his head. "Sure, that might be useful."
"Request a-acknowledged. Tour-r-r screen now onl-l-line." A massive screen flashes to life in front of them, and they're suddenly looking through the creature's eyes at miles and miles of coral reefs growing on top of what look like the ruins of an ancient city. Creatures swim around them, lights similar to Lighthouse's flashing nearly everywhere
"Wow," Jacob says, leaning forward. "This place is pretty. I wonder where we are."
Mike carefully scans the reefs for danger. "Doesn't matter, as long as we can get this done and get back home safe. Don't forget, we're in a vulnerable situation here."
"Always business with you, boss," Jacob sighs. "You're right. I'll get this thing ready for refueling."
"Good. Keep it up," Mike replies. "Hey, Lighthouse, is it much farther?"
"We should ap-p-proach the ma-ainland gates in ab-bout one minute. You m-may exp-per-rience slight pa-a-ain when we reach the g-gate depths."
