Invitation to the Hunt

It sounds like Fury might have a job for you. She wants you to meet with her sister. Here's what she wrote.
"Hi, buddy! I'm not good at writing letters, so I'm sorry if I'm doing this wrong! There's something that should interest you. It's about the worm, darn it! We've had enough of it. So we decided to deal with it once and for all. Want to learn more? My sister Reya the Merciless will explain all the details. Anyway, come over here, we'll tell you everything!"
You should pay a visit to this Reya.

Hi, greenhorn! So we meet again... Look, this desert is a dangerous place - almost as dangerous as the Astral. There are treasures and monsters! One of them is Uro-Boros, a huge worm that has been terrorizing the neighborhood. But we are the Landfill Warriors! Nothing scares us. I'll give you a thing, it'll come in handy for what we have planned.
