20k Leagues Under the Sea: Alcheme

[The elevator deposits you in the interior of a spacious submersible with a decidedly steampunk aesthetic. All of the metal is brushed bronze, and the navigation tools look to be turn of the century]
[Through the periscope, you can still see the sky; the water visible through the circular windows is a pale blue-green, kissed by filtering sunlight]

ROUND 3
"This underwater crater spews lava, but not flames. Flames need oxygen from the air and are unable to spread underwater; but a lava flow, which contains in itself the principle of its incandescence, can rise to a white heat, overpower the liquid element, and turn it into steam on contact. Swift currents sweep away all this diffuse gas, and torrents of lava slide to the foot of the mountain, like the disgorgings of a Mt. Vesuvius over the city limits of a second Torre del Greco."
[You take in the sights through the portholes, beholding the wonders of the sea. All around you, your submersible hums like a well-oiled machine, performing the duty of keeping you safe most admirably]
[At this depth, the pressure is beginning to increase. It will be more dangerous to continue from here]
ROUND 3 DISCUSSION
[Are you ready to continue your grand journey to experience the undersea world and all its wonders? y/n]
[Please roll a 1d100 and submit your result with your decision if you plan to continue]
[To try for the keepsake, please roll another 1d100]
