Red Gas
Red Gas is the nickname given to the substance called Velum Sanctuarii ("Holy Veil"), a chemical weapon deployed against the Kindred by the Second Inquisition. It has effects on Kindred flesh similar to exposure to the sun, making it a dangerous weapon indeed. Although it can be avoided, it can be used to herd Kindred away from a place, or can be used to surround Kindred and herd them into a smaller place, where they can be eliminated by ambush teams.
It is produced and controlled by the Order of St. Leopold, who keep a tight lid on the true nature of its function and composition. Red Gas smells of sandalwood and myrrh, and most Kindred survivors have reported hearing wailing voices, perhaps those of their victims, in the gas. The Ashirra claims the effect is similar to the Keening.
The Red Gas does not affect humans, and indeed they may not even perceive it. Red Gas may have been used in the 2008 attack on the Vienna Prime Chantry, with witnesses claiming "Red rain and smoke poured out of the ordinance, melting cold flesh from bone."
Background Information
- Most Battle Royale games incorporate some method of constricting the playfield. The Red Gas serves this purpose in VTM: Vampire: The Masquerade - Bloodhunt . Unlike the constricting circle of games like Fortnite, the flow of the Red Gas is partly influenced by atmospheric conditions and the structure of the city itself.
