As we enter Strangetown just on the outskirts is a street called Dead End  Lane where a large estate holds a mass of what appears to be graves. But looks can be deceiving. This is known as the Specter Estate where an "old" woman Olive lives with her niece Ophelia.  The word in the hood is that Olive killed all those people which include her sister Willow, brother in law Creon, husband Ichabod, the neighbors Lyla Grunt and Glabe Curious.
Under the what appears to be a cemetery is actually a bunker issued by the military and was being used as a testing facility by not only the Military but the Aliens from the planet Vectron. Olive was recruited to get tests subjects under the guise of being a Professional  Party Guest well between you and me  we know what that is!  Between the Military, Birth Queen and Pollitech 9  she had no choice but to get the test subjects.  First, they took her family, parents Loreto and Peponi Muenda, Sister, brother in law and husband.
The next thing that happens is the arrangement for the Social Worker to come and take her child Ghostly and put him in the care of 2 of their Doctors Loki and Circe Beaker in which they treat Ghostly as a test subject. Poor Ghostly becomes neurotic so they begin to call him Nervous  Subject.  
So it was up to Olive to get the subjects for the Experimentation that not only was the Military and Aliens involved but also the powerful corporation SIMPE.  She had no choice so she got them their people any way she knew how through being a "Professional" oh excuse me a party guest. They told her that she could stop after a quota of about 20 were involved.  This absolutely drained the life out of poor Olive for not only was she to recruit subjects for them she was also their caregiver.  Over the years there were many investors in the company including families from neighboring communities such as the  Goths from Pleasantview who were apart of the program, as well as the  Landgraabs from Bluewater Village, The Monty's  and the Capps from Veronaville and  the list goes on.
Once Simpe,  the military and the Aliens from  Planet Vectron were finished with their probing and experimenting they abandoned the bunker. Leaving their test subjects there to rot.  Once Olive caught wind of this ever so slowly she began extracting the people from within.  Lyla went home to Buzz and their family her parents took one of the children Melissa and moved nearby,  Glabe returned to her daughters  Lola and  Chloe, the rest returned back to their lives memories of the facility and what had happened were completely erased from their memories.  As for Olive after releasing everyone from the bunker a tremendous amount of weight was lifted from her shoulders and the aging process reversed itself and before she knew it she looked and felt young again.    And right in front of her was her husband  Ichabod and  Ghostly waiting for her to come  and help  with some potty training business.
