Effects of player actions
When Obadiah first meets the player, he is polite, and asks the player to sit down and chat. Obadiah sits in a wheel chair, next to a pair of gas canisters and crutches, signaling that he is disabled. It is here where you activate the quest "The Dark Heart of Blackhall" wherein you are requested by him to retrieve The Krivbeknih. However, once the player completes the Dark Heart of Blackhall quest, it is shown he is fully capable of walking.

Obadiah can be seen praying, in his basement, in front of a dead Creeper, after completing the Dark Heart of Blackhall. The player is then given the option to engage in conversation after his initial disapproval and request that you leave his home. You are then given three unique choice options. When the player states he hides bodies in rivers, he responds by saying he and the player are more different than they can comprehend. Telling him that you thought that he was above "this occult nonsense" will cause him to tell you that you misunderstood and demean you. A third option will cause the player to tell him that you will leave and he tells you to make haste.

Behind the scenes

 * Blackhall and the mission related to him is a nod to the works of H.P. Lovecraft.
 * The Blackhall family is a reference to the Whateley family from the H.P. Lovecraft story "The Dunwich Horror." This is shown as the player can alternately end the quest at the Dunwich Building's altar.
 * There are also similarities to the central family in "The Lurker at the Threshhold," the novel Lovecraft co-wrote with August Derleth, who published it after the former's death. As with there, an aristocratic man inherits his family's dark legacies.
