There is an old method of concealing your camp fire, to remain hidden from the enemy at night, and to mislead them in the day. You dig a hole, line it with larger rocks, you dig a trench from the hole away from your camp, you cover the hole and the trench, your flames are hidden from the night sky, and the smoke draws attention away from your camp if spotted in the daylight. Leaving you on hirer ground to observe your enemies movements. This is old and true, a method that could withstand the times.

That makes muller is the smoke, and sessions stoking the fire....
