I have a Wrath of Sithis script created for me by Chesko, but he did not have the time to hook it into the Dark Brotherhood eviction script.
What I need done is... making it so that the Wrath of Sithis appears when the player sleeps after breaking one of the Five Tenets. Currently, it is only possible to make this happen by entering a start quest code into the console.

I do not want to share the script here, so if you can help me, let me know and I will PM it to you.
