3 years ago, remains of a large pyramid 

were discovered on the back side of the property.  The owners dog found the top of it when it was digging in the dirt.  After an archeological team was brought in, they discovered that it was a giant pyramid, similar to the Mayan pyramids in Central America.

After months of excavating, a unique and tortured past was uncovered.  The site was once inhabited by a previously unknown tribe of Native Americans, known as the Neztekian.  The site contains the remains of possibly millions of victims, thousands buried in mass graves, and many others left impaled on 12 foot spears.  The paintings inside the pyramid uncovered that the Neztekian performed human sacrifices on the site, massacring thousands of people over a period of about 1000 years, in ways very similar to the Maya.

The site also contains Arkansas' oldest graveyard.  The graveyard contains the remains of dead Confederate Soldiers, who all died on the site in 1865 during the closing hours of the Civil War.  A forgotten last battle was fought here, when the remnants of a last Confederate Division of calvary held up on the grounds after the war had been officially declared over.  Defiant and refusing to surrender, the Union troops destroyed the Confederate soldiers and buried them all on the site.  The grounds contain the remains of some 20,000 Confederate soldiers.

The owners have reported ghostly sightings of what they believe to be the dead Confederate General who had held up on the grounds in the daring last stand.  The Confederate leader, General Thorogood, was decapitated by a Union soldier, when he cut his head off in revenge for what the Confederate General had done to his comrades.  The owners have reported many ghostly sightings of the headless general, roaming the grounds at night.

2 weeks ago, the workers of the site began reporting strange disturbances and paranormal activity.  Many refused to discuss what they had encountered and some refused to continue working.  After 4 other workers were found dead, all impaled on the 12 foot spears, the remaining workers left the scene and would not discuss what happened or what they saw. 

3 days ago, investigators went in to see if they could uncover some answers. They have disappeared and have not been heard from in over 2 days.  Your mission, if you decide to accept it, is to go in and try and locate the lost group of investigators.  Rescue them if you can.  Your safety cannot be guaranteed.  Enter at your own risk! Good luck!
