Obadiah Blackhall

 is one of the inhabitants of Point Lookout. Living in the estate of his family, Blackhall Manor, he despises the other inhabitants of Point Lookout to varying degrees, either because he considers them uncivilized or simply dumb.

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 front of a dead Swampfolk, after completing the Dark Heart of Blackhall, and when the player states he hides bodies in rivers, he responds by saying he and the player are more different than they can comprehend.

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).

Trivia

 * 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."
