Dearest mother and father,
How have you been?
Please forgive me for replying so late. There's been lots of trouble in the Underworld, and the orphanage is overcrowded with the injured, so I haven't had time to do anything apart from treating the wounded. I even had to send some of the younger children to foster families in town, because I didn't want them to see the carnage inside the orphanage.
As for your previous question — yes, I've heard rumors about the Supreme Guardian about to order a blockade between the Over- and Underworlds. I understand your concerns, but from my point of view, there is no way I can abandon the people down here right now. During this extraordinary state of panic, I can only hope to use my modest skills to bring a modicum of comfort to the needy.
Fortunately, I know you'll respect my decision. I still remember when I was fresh out of college and Dad told me, "Anyone going into medicine to just get a decent job will come to regret their decision sooner or later." I think I understand more than ever what you meant back then.
I don't know when we'll ever be able to see each other again, but I hope you can be healthy and happy. Your daughter is a big girl now, and can take care of herself, so you don't have to worry about me.
Your daughter, with love, Natasha
