Found in a rotten box under the Old Bridge.
J'Ghasta is dead! Well done! I was right about you, Silencer. You are a useful tool indeed. Let's see if you can continue to impress me.
You must journey now to the Flooded Mine. There you will find Shaleez, an Argonian hunter who was banished from her village near the Black Marsh/Morrowind border for the brutal murder of a Dark Elven family. Relatives of the murdered family members have located Shaleez, and demand retribution. And, since the assignment is a bit far for Morrowind's Morag Tong to handle, the Dark Brotherhood has been commissioned to perform the elimination.
Be warned, Silencer! Shaleez is a skilled and deadly hunter, and will fight like the desperate fugitive she is.
