According to Dead Drop Orders 3, J'Ghasta is the next target for the Hero. When the Hero walks in his house, and the area where the most blankets are is visited, one will see a hidden trap door to J'Ghasta's basement. When the Hero gets down to the basement, they must kill J'Ghasta.
"I don't recall inviting you into my house. Leave, quickly, or we will have a problem."
- We already have a problem, J'Ghasta. "What? Who are you to come into my home, to speak to me like a petulant child? Do you know who I am? Do you have any idea what you're dealing with?"
- Oh, but I was invited. By Sithis! "Sithis? What is this treachery? Who sent you? I don't know who is behind this outrage, but I will have blood! To the Void with you, assassin!"
- [Say nothing.] "So, the thief opts for the stoic approach, hmm? Oh, my friend, I'm afraid you've broken into your last house. Ha ha ha ha ha!"
- After J'Ghasta dies, the Hero can go back up to J'Ghasta's beer keg and lockpick the Very Hard lock. In the keg is a set of Black Hand Robes and a Black Hand Hood, proof of J'Ghasta's involvement with the Black Hand.
