Like Josh Petrie said, you declared functions in a header file that were never defined elsewhere. I have enclosed 3 of your project's file code with the error fixed.
You will noticed a few things:
1. I have created the Prologue.cpp file and moved the content from Char info.cpp to it.
2. The prologue is now used as a class instead of static. See the modification i did to Main.cpp to notice it's scope remain inaffected.
3. The fonctions and member variables of the class Prologue are no longer static. Prologue.cpp now have the proper definition of thoses fonctions, and a constructor aswell.
4. The file Char info.cpp has been deleted.
