Last year, during summer and then again in the winter, we released two small modifications for players who bought The Witcher 2: Assassins of Kings on Steam [Modifications of Signs: Quen and Aard]. Today we’re bringing them to you as a single update for all versions of our game. Both of the in-game changes must be triggered properly before using them, and we've included some clues below if you’re in the mood to solve some riddles:

“Midaëte, or Midsummer, is the day of the summer solstice and marks the beginning of the first month of summer in the elven solar calendar. Elves believe that all things under the sun occur in cycles. After Midaëte the days grow shorter and the dying commences - to last until the winter solstice. Summer Shrines erected on this day give praise to the sun and life, while acknowledging death's certainty.”

“After Midinváerne, or Midwinter, the day of the winter solstice, the days grow longer. According to the elves, Midinváerne marks the beginning of a new cycle: the sun gradually gains power and all things beneath it are born once again. Winter Shrines erected on this day celebrate the revival of light and life, but also honor the winter, as death and resurrection are two sides of the same coin.”

Alternatively you can refer to posts and comments #1 & #2 for clues on how to activate them if you’re short on time.
