Dark Brotherhood

YOU! YES, YOU! Shh! Come closer, I have something for you...
It’s a letter from a stranger in a black robe. He said I was supposed to give it to you. Apparently, there’s something important in it. See you later.

In the letter:
"We know you are lost, child of Sithis. We are calling you home, to the last functioning sanctuary of the Dark Brotherhood. There are not many of us who survived the Brotherhood’s purge. That is precisely why we need every survivor. We are calling home all who are lost, all who are confused, all who have survived. We call upon you, brothers and sisters, in the name of our Dread Father! We will be waiting for you.

Hail Sithis!"
