Amethyst works for a geological surveying company, following and mapping promising veins of ore, useful minerals, or deposits of magical or precious gems. And sometimes that work takes her underwater - which is fine, she quite enjoys scuba diving, and she’s taken enough classes to feel comfortable doing it.
 
Too bad she didn’t take a partner, though. Maybe if someone had been watching her back they could have warned her before the tentacles got her wrapped up, nice and snug. At least the big beast isn’t hungry - at least, not for food. It might be quite a while before it lets her go free~
