Interactions with the player character
When the 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. 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.

Bugs
Obadiah will not show up on your compass as friendly or hostile (even with a 10 in perception). This can be quite disconcerting due to the fact that he engages you in conversation, especially since you are under the assumption that his home is merely abandoned. Obadiah is meant not to be located once the player finishes the exploration of black hall manor. Thus, its located in a corner of the room holding the crippled man, showing him by the exit of the stairs (he seemingly can be found with his eyes closed on his wheel chair, which means he is/acts crippled).

Behind the scenes

 * Blackhall and the mission related to him is a nod to the works of H.P. Lovecraft.
 * The Blackhall family is likely a reference to the Whateley family from the H.P. Lovecraft story "The Dunwich Horror."
 * 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 inherrits his family's dark legacies.
