Serums are the liquids used to induce illusions known as simulations. They are either taken orally or injected into the body through a syringe. They are clearish liquids that occasionally have a slight tint to them. The Divergent are not affected by most of the serums and they remain aware that they are in a simulation. Serums can be injected individually or airborne. Most factions have a serum for their own uses.

Types Edit

Many more are unnamed.
