A tightly sealed letter left with Sugriam from a Gnome dressed in black, he leaves it with him telling him to open it making sure no one else knows the contents
Dear Mister Sugriam,
I will begin by introducing myself, I am Indigo. I have some questions you may be able to answer. I wonder if you are an illusionist? If you are, you must give praise to The Master of Illusion. You seem to be quite a successful merchant creating some of your own wares yourself. You must be interested in participating in The Cloaking. I expect you to speak to no one of this. I will await a reply. I am reachable at the Shrine of Ascension.
-Indigo
