Hi Tina!
You know you have crossed the wrong part of the river by the smell. You follow the markers and enter a house where people are super nice, I mean just superdy duperdy smiley nice. And you have to wait in a cave cause "the bad people are all around" and you smell a smell most living people never have smelled of rotting humans but you dont know what it is yet its just bad. And you wait in that cave, and no one brings any food and you dont know how long you have been in there with a bunch of others and some of you die. Then they come and you are so weak you can barely move and theres no stars or moon and you cross a river.
