Be *resting* at the balcony around 7.00 pm and you get the mark, only one person in the room will get the mark. Sitting does not work.
Note: Other people in the room, either with mark, or outside the level range can prevent you from obtaining the mark.
For experiencing the farewell of another day in such unusual fashion, the Powers have granted thee a Mark. You have been granted the Mark of Dusk! You gain 56 practices!
