I wanted to write a story behind it, but I couldn't get it right :( if you'e interested in what happened, I can tell you that she went exploring some old ruins and found something that didn't really want to be find. To distract it from the rest of the group she run the opposite direction, but didn't take into the account the fact that even being the fastest runner in the group she can't outrun it. So instead, beaten and scared, she jumped down into a well hoping there's enough water there to slow her fall. Obviously, there wasn't.
