Dearest Uncle Duke,
It brings me great pleasure to tell you that I have finished the program of education set for me. With that in mind, I am ready to assume a position in the Spellguard, if my service is wished. I would be more than happy to accept an entry-level position of some kind, as an assistant or a researcher, if you do not deem me yet worthy to wear the title of Agent. And while I plan to continue my studies (learning is never done!), I hope that this also means I will have a little extra time to visit with you, as we used to do.
Your doting niece,
Beatrix
