I came to Harvestella for the farming, but stayed for its intriguing mysteries

When I awaken in Harvestella, the first thing I notice is the hazy, sepia hue of the world around me. Specks of dust float in the air above, and a strange crystal-like formation juts out against the grey skies behind me. I don't know how I ended up in this place, or why I was lying on the ground outside, but I'm beckoned by the very same mysterious winged figure who roused me from my unconscious state. I begin by heading down a small, empty village street. Everything is quiet, and I appear to be alone. Upon inspecting the door of a house nearby, the voice of a child responds. "Big scary monsters will gobble you up if you're outside when Quietus comes", the child says from the other side. The inhabitants of the house adjacent also don't dare emerge right now. It's clear that being outdoors at this point in time is not the done thing, so just how did I come to be in this situation… and what is it about "Quietus" that scares everyone so much?

I continue to head towards the otherworldly figure who appears to be trying to help me. They declare that I will be the one to save the world, and that I'll understand more in time. I don't have any idea what is going on, why the world needs saving, or who I am for that matter, but I can't deny I'm instantly intrigued. After some more ominous words, I'm soon met with the sight of a glowing, red light that radiates from big crystal shards protruding from the mountains on the horizon. Suddenly, I collapse to the ground, and so many questions hang in the air. As a fan of farming sims, I stepped into the Harvestella demo for its agricultural offerings, but its opening moments hook me into the several mysteries I'm now determined to solve.
