Excited Vibrons are one of several species of exotic particle in the Vibron family - obscure elementary subatomic particles that contain, transfer or release heat as vibrational energy. Excited Vibrons have been slowly brought to an elevated energy state within a series of complex magnetic fields and exotic alloy containers, and occupy a metastable energy level, which is easier to contain and transfer the particles in. When transferred to the particle distributors of most standard Energy Fields, they slowly radiate heat energy into the surrounding environment, mitigating the impact of cold environments for a time. If the Energy Field loses coherence, however, the Vibrons in that field quickly disperse into the surrounding environment.

Excited Vibrons are type of Exotic Particle - an Exotic Substance related to Etheric Science. A physrep of some kind of energy containment device can be used to represent up to 10 measures of this substance, but particularly large physreps can hold more.

A measure of Excited Vibrons can be applied to an Energy Field to provide some protection from Minor Cold-based Conditions. This stacks with other sources of protection from Cold Environments. If you are entering a Cold Environment, the Encounter Referee will usually let you know, and may ask if you have any relevant protection. Even if the Environment effect is more powerful than this substance can protect from alone you will still have greater protection than none - you may be able to go longer before suffering a Condition, or may suffer a reduced version of a Cold Condition. It is important to note that this substance does not protect against weapon attacks or other direct sources of harm - only to the more distributed hazard of a Cold Environment.

As with all Exotic Substances, a character with at least 1 rank in the relevant speciality (Etheric Science in this case) can spend 1 minute of appropriate roleplaying to apply 1 measure of Excited Vibrons to an item. After this roleplaying, they should unpeel the sticker that represents this substance, stick it to the lammie of the item being powered-up, and record the current date & time on it.

The boost provided by this substance wears off 1 hour after application, or if all Field Hits provided by the Energy Field are lost (usually through damage), whichever is the sooner. If your character is in an Environment causing Cold Conditions when this substance wears off, you should notify the encounter Referee, either as soon as is convenient, or at the end of the current encounter.
