Fog Realm was one of the Realms created by the Accelerons. It is a realm that is filled with fog that blocks the driver's view of gigantic obstacles and treacherous switchbacks, and causes collisions as well. Theories point out that Dan Dresden was lost in this realm and was rescued by the Silencerz or had his memories inserted in the RD-L1.
An AcceleCharger will grant the driver to see in the fog.
