Translated publisher's blurb:
"'Dar Drugiej Siostry' is an adventure set in the pagan-ridden forests of Matra, in a nobles' court, where the players characters are guests. Invited to a wedding party, the Heroes find on a nearby, small family cemetary... the grave of the bride. This marks the beginning of a dark story in which they will slowly gain knowledge of the history of the Mornello family, a history in which nothing is simple - either black or white. Private dramas of ordinary people mix with the history of the Queen Mother's country and the turning of Matra to karianism, and to top of that, an ominous presence of magic and Darkness.
The players will have to make many choices - standing against fallen, but once noble people and also an evil, that perhaps stems from good intentions."
