Sauna - Finnish Ritual

It's 3pm and the setting sun is already touching the crown of evergreens far in the horizon. Soon the dark will swallow the white landscape before your eyes and turn into dark blue hue. Your friends have already gone to their houses, leaving you on this small island on a frozen lake. They have already survived the night you are about to enter. This is where you will become a man, a Finn. It is said that everything you need, in order to survive the cold night, is hidden in this small piece of land. There is a small sauna near the shore. It's your only hope to get warm enough but it seems to be locked. In the dimming light you spot some pieces of firewood in the distance. You have been told there is also a well somewhere.
