Ορός του Θανάτου

The Death serum is a substance used by Jeanine Matthews. When Tris surrendered herself for testing, Jeanine attempted to use it, but it was actually a different, non-lethal serum dyed purple. The real serum was in Peter's hands. It is also noted that strong Divergent characters can resist the death serum when Tris resists it in Allegiant.[1]
