The Mountain Trek Oneshot? Perhaps threeshot? Perhaps more?

Every year, sometimes more, King Arithem sends out a party, whose sole purpose is to continue the Search for his missing children. The Search has been going on for 19 years. The Search has come up empty for 19 years. But the Search continues. 

You set out on the Search three months ago. Everything went fairly well in those first days- trekking through forest and mountain, searching for caves and valleys not yet searched. But if it had been that easy, someone would have found them already. 

The strange things started a month ago. Figures passing by in the night, sounds for which you could not find a source. But now, on this journey, you are in the thick of it. Those things seem trivial now. Now, in the midst of the mountains, the horrors have begun.
