[ The letter has apparently been written quickly, with a drop of a blood on the bottom]
Esteemed Rahmun,
Due to unforseen circumstances, I am no longer able to assist in the matter to which I was hired. While I understand this puts you in a difficult situation, I hope you understand that I would only break a contract under the most dire of situations. I wish you luck in your coming challenge.
Signed,
Makilith
