Red Fog

The Red Fog, which has no formal name, is a technology brought to Earth by the Madgod.

Its origins are unknown, though its function is clear.

It is spawned from various dispersal units throughout multiple cities under Vanguard Control. It has many uses, from entertaining to deadly.

First and foremost, it primarily acts as a poison for the Undead, regardless of category. It's only lethal after extended exposure, but Undead have to be confined to vented rooms, or must leave the city entirely.

When a city is engulfed in the fog, it's usually a beacon of safety for anyone fleeing from war with the Undead or a haunting.

It can also be used for entertainment purposes, as the fog lights up in larger cities. It gives the city an exotic and alien atmosphere, which is ideal for The Citadel in Virginia.
