It's been three years since you returned from Narnia, and in that time, you and the Pevensies have been inseparable. You and Susan have grown closer than ever, and you and Peter have even bonded quite closely. You exchange letters with them often, and they are usually filled with reminiscent tales of Narnia, though Susan refers to them more as stories than memories these days. Edmund has hardly left your side since you left Narnia, and Lucy is like a sister to you. You've all grown up quite a bit, especially given the war.
In recent months, you and Edmund have graduated secondary school, Susan is now living in America with the Pevensies' mother and father, Peter has gone back to live with Professor Digory Kirke and study under him, and Lucy is still in secondary school.
What with the war and the Pevensies' move to America, Edmund and Lucy are currently living with their relatives, the Scrubbs, in Cambridge. Luckily, you are in university at the University of Cambridge, as is Edmund, so you only had to be apart for the few weeks between graduation and the start of university.
This is where the story resumes...
