Sihy the errors of not finishing quest has to do with your savefile itself
mine also old one so that doenst change until you start a fresh one but not effect your game in general
the Familair is the imp you get from the tower after fininshing the stuff with the spider queen
And people keep in mind, with the test version, in the Map walkthroughs there is the file explaining lots of the questions that been asked here. How the imp evolves and such.
when the compressed version is out, when the officole 2.41 is done, due bugs and images are still missing. that is the same for the andriod version aswell.
