Only the Paladin can help the Rusalka. The Fighter, Wizard and Thief may befriend her, but cannot free her spirit.
The game plot takes place in Eastern Europe; the season is winter; the central element is Water; the mythology is Slavic.
Unlike the previous three games, in this game no Dispel Potion is used.
The title for the game: "Shadows of Darkness" was originally planned for the third game in the series, but the creators decided to move the storyline back in the series and add another chapter.
After the game was released with a number of bugs that were eventually patched, the series languished for a while despite the ambiguous ending and hints at a sequel. A fan-made project eventually revived interest in the series and was able to motivate the production of the fifth and final game in the series.
