About
The 7th Child Development Facility, "Eden." A clean white building, beautiful gardens, and warm meals. Every child receives an elite education and departs for society at age 18. The children wear pristine, all-white clothing.
However, a small sense of unease lurks beneath the peaceful daily life.
No letters ever arrive from the graduates.
You ask the Director.
-- "Where are the children who graduated?"
-- "Everyone is working hard in their respective places."
What lies beyond the walls of this orphanage--?
