As you make towards the edge of the forest and you can see the classical ill sign of thick fog crawling out of the thick foliage of the trees. You heard tales of these woods and the fact that the Three Kingdoms consider this place forbidden does not sit well with you. Tales of fae, ghosts, witches, and worst makes your raise.
The guards armed their crossbows and aimed at you. They take you out of the wagon one by one which to your young thief is a good sign. She had gotten a few leery stares from the younger guards.
Strange men in expensive garbs had emerge from their comfortable looking wagon. They are holding metal rods with the tips have glowing white hot azoth. The guards begin to strip you naked till your backs are exposed. Then these guards firmly plant you all on the ground by force like your animals ready to be branded. Oh you were branded. When that azoth touched you the pain was like being strike by lightning and burning alive all at once. The pain felt like it took forever. When it was done all you can do is lay there and silently cry. Through the tears you see other cage wagons arriving and with the same treatment before passing out from the pain.
Next day you wake up in your cage and ordered to leave the wagon. There is about a twenty other prisoners outside of group. Their backs exposed with the same markings you have. Finally the guard captain speaks.
"If you want to escape, then escape."
