This is the ’sequel‘ to „Relations“ and „The Price of Peace“. Voldemort is dead. So is Ron. But Harry has for the first time a possible life and a future. Nevertheless Dumbledoor calls on him and his friends to save the day. They have to man an expedition to an paralell dimension to destroy a crystal sprout, that can be used to control people more completely than Imperius. The destruction goes of without a hitch but there is the memory from Riddles diary, that escaped through the portal into Ynulle instead of „dieing“.
There is also the interesting constellation of Hermine, Harry and Luna.
The story can be read at Schnoogle.
I also made a PDF out of the Story.
