Hamud's Last Testament
My daughter,
My periods of lucidity now last only a few moments at a time. I am sending this note to you with one of the new recruits in the Tenebrous Edge. I am unable to leave my chambers in this ancient, cursed fortress. I know now what will become of me. The Dark Master himself spoke to me and told me what lies in store. I know I will never reach the gardens of delight spoken of by ibn Salayyar. In my years of service with the Zharalim, I became familiar with many horrors, but what awaits me now surpasses even the depraved rites of the Milantans.
Do not fall as I have fallen, my daughter. Seek a way to escape Dereth. I have heard that others have disappeared from this undead world. My hope is that you will find a way to disappear as well.
Your devoted father
