Good atlases are defined for effective orbifolds, and a spark complex is constructed on each good atlas. It is proved that this process is 2-functorial with compatible systems playing as morphisms between good atlases, and that the spark character 2-functor factors through this 2-functor.
Keywords: good effective orbifold atlas, compatible system, spark complex, spark homomorphism, spark homotopy, spark character
