Included with the note below are two carved wooden figurines; one if of an eagle and the other a raven. Each is rather intricately carved and will fit in the palm of Amelia's hand. The animals were chosen because in Druid mythology the eagle is a symbol for protection against evil and the raven is a symbol for healing.
Dear Ms. Amelia Bones,
Forgive me for introducing myself under such terrible circumstances, but my name is Aberforth Dumbledore and I reside at the castle. I am writing to you to inquire after your health. For while we are not friends or acquaintances, news of your situation has moved me to reach out to you. I am truly sorry you had to encounter and experience something so horrendous and am heartened to learn that you are recovering. If there is anything within my capacity to do to help you, I urge you to let me know. I would be more than happy to assist you with whatever I can.
With my sincerest regards, Mr. Aberforth G. W. M. Dumbledore
