The first three letters. Unsealed. In cerulean ink, they say:

Lucy,
You know my dreams as well as I know yours.
I never lie, you know this. And you trust me. And you have done well by me to listen to me.
Have I ever failed you?
Now, I say your dreams will soon come into being.
I know you do not believe me, and I do not blame you.
I am only telling you.

Lucy,
You think too much and worry not enough.
Though I do not condone it, I will not stop you. It is your decision to make.
Worry not; you will be unchanged to me.

Lucy,
The world is full of many wonders. You need only look.
Now, you have looked and see for yourself and are burdened with knowing.
Now you know, just as I do, that all are waiting to be found by you.
Know also that a great magician awaits you.
