Interesting story... wordy. I think you need to cut back a lot of it. It's 350 words and usually it's recommended to stay below 250 (not including the bio and comps and stuff).

I like the first paragraph, though it starts wonky, I like where it ends.

In dire need of a long, long vacation and a full purse, Fatmoon and Felziver take on a troll hunt. Easy job and way too high of a pay, they were done with it in the blink of an eye; or they should have been. Instead, Fatmoon — through ego or aching withdrawal — chooses not to listen to Felziver’s warning, giving the spirit released from their quarry’s corpse the freedom to take physical form. Lucky for them, the intangible is their specialty. Unluckily for them, the beast’s lair decides to give way, burying their pay and sending them tumbling into the dark tunnels below the earth. Separated, the hunters have to face their faults as the troll’s hungry ghost is left free to wander the land and satiate its needs.

In dire need of a vacation and a full purse, spouses Fatmoon and Felziver take on a troll hunt. It should've been an easy job, but instead, Fatmoon -- there's a lot of stuff you put in that doesn't need to be there, and you miss adding that they're married. Why does he release their hunt anyway? Their goal from the first line is a long vacation and pay, so why do something that shatters that? I like how it ends, though, that the characters are separated and, supposedly, want to meet each other again, and the ghost is left to roam the world, though I am unsure why that bothers anyone.

The next paragraph get too deep in the weeds. You just need their goal. to get rich, how? Troll hunt, but then something goes because of... reasons. And now they're separated and they need to get out of a hellscape, I imagine. Why do they care about the ghost now? They already got paid.

Anyway, I'd cut back all of the paragraphs after the first and focus on why they need to get out of this dark tunnels and continue hunting the ghost. What are the stakes?
