Marcella

S. Marcella J. is one of the inhabitants of Point Lookout in the year 2277.

Background
She is a Christian Missionary from the Abbey of the Road who has set up shop west of the Pier in the Disaster Relief Outpost.

Her terminal mentions her travel east from the Abbey to the Commonwealth. From there, she took the Duchess Gambit south to Rivet City where she met up with Father Clifford before finally arriving at Point Lookout.

Quests

 * The Dark Heart of Blackhall: This quest will be initiated when the Lone Wanderer encounters Marcella upon exiting Blackhall Manor. She will ask the player to find the Krivbeknih and take it to Dunwich in order to destroy it.

Effects of the player's actions
After you find the Krevbeknih, she will be found dead inside the tent (she was killed by a trio of smugglers for unknown reasons, although it is implied that Obadiah Blackhall hired them as mercenaries to kill her, as she was chasing after his book).

Appearances
appears only in the Fallout 3 add-on Point Lookout.

Bugs
Sometimes, right after the player encounters Marcella, an albino radscorpion will appear and kill her instantly. This makes her route of the quest impossible.
