Parting is Such Sweet Sorrow
Chloe genuinely despised writing goodbye letters or saying goodbye in the first place, and found informing people of someone's departure in Amat to be one of the most unpleasant and onerous duties imaginable. but, over the years, she developed a certain apologetic and contrite streak that made her feel that she owed at least certain people a series of final apologies before she left. Here they are.
To Hermione
I will pray always that my fears were wrong, that I did not fail you at the last, and that you are back with your friends, fighting that foolish war of yours, that Poseidon did not take you as he swore he would.
Be safe, my friend.
-Chloe
