Notum is an anomalous alloy of several common metals that has a faint silvery blue colour. It forms due to a poorly-understood interaction of interstellar radiation with metals on the crust of rogue planets. It is more prevalent in the Orion Nebula due to peculiarities of the background radiation there. Notum is an alloy with highly irregular structure - seems to contain “electrical organelles”, which may be bio-metallic.

It has several interesting properties, including the facilitation of energy transfer in a manner similar to biological cell organelles, in metallic crystalline analogues. It is also mutagenic, and interacts with the nervous systems and energy transfer mechanisms in many biological organisms.

Naturally it forms exclusively on Rogue Planets - the interaction of unknown cosmic radiation on crustal metal deposits. Initial seeds caused by the interaction of deep space particles or energy on unprotected rogue planets can slowly spread over millennia due to recrystallisation in certain minerals, causing notum alloy to form, as silicon and oxygen atoms are pushed outward to form hard quartz and other silicates crusting over nodules of metallic notum alloy.

Notum can be “bred” on a nano-scale with specialised nanites from its constituent metals. The process is very slow and requires extreme precision.

Notum is a type of Exotic Reagent - an Exotic Substance related to Corporeal Science. A physrep of some kind of blueish metal can be used to represent measures of this substance, smaller amounts can represent one or two measures, while larger physrep samples can hold more.

A measure of Notum can be applied to any one Device (Weapon/Energy Field/etc). Applying a measure of this substance to a device will temporary allow it to spend its Charges to RESIST the device being affected by the SUNDER call. If a device enhanced by this substance is affected by a SUNDER then you may spend 1 Charge to RESIST it. Once applied, the Notum lasts for the remainder of the day.

Notum also has a specialist application as fuel for the more powerful Advanced Programs of Notumi Corpori Nanodecks.

As with all Exotic Substances, a character with at least 1 rank in the relevant speciality (Corporeal Science in this case) can spend 1 minute of appropriate roleplaying to apply 1 measure of Notum to a Device. During or after this roleplaying, they should unpeel the sticker that represents this substance, stick it to the lammie of the Device, and note the date on the sticker. After the day has ended, you should remove the sticker.
