SKT: The Lost Laboratory of Kwalish
As the airship draws closer the monastery and the floating island it is on becomes clear. Floating hundreds of feet in the air at the center of the valley is a large island of rock. Enormous chimney engines extend from the bottom of this island, burning with fitful, deep-red fires that appear to keep the island aloft. A series of odd structures rise from the rock,
appearing almost like metallic crystals.
Farther down the cliff-side ledge is a flat metal dock, on which reclines a feline monstrosity with a female humanoid head—a regal gynosphinx. A matching dock is thrust out from the floating rock island across from this dock, but there is no obvious way to cross the hundreds
of feet of open space between them. The gynosphinx notices the airship and flies up to intercept it to ensure that those on the airship can't reach the monastery without passing her test.
The gynosphinx appears to have suffered ancient injuries to its head, which have healed and been replaced by mechanical components. Both the creature’s eyes are now glowing blue lenses, and its head is orbited by a number of spinning metallic devices.
“While it is clever to use an airship to try to fly to the monastery, you still must pass my test. So entreat with me,” the sphinx says, “if you wish to cross to the monastery. You do not appear entirely ignorant, and I look forward to adding whatever small knowledge you might possess to my collection.”
