Abilities aren’t just telepathy, empathy
Telepathy, empathy, kinesis, and precognition are chief among the so-called ‘mainline’ Abilities recognised by the IESRO. Because the IESRO regulates the most powerful Abilities across multiple species, their primary interest is the Abilities that manifest with recognisable consistency across species lines.
Among all species discovered to date, some form of empathy is the most common: the ability to communicate basic non-verbal concepts within a species and to others. Telepathy comes a close second, but because telepathy is primarily the ability to communicate complex concepts mentally, it can be hard to recognise cross-species as the underlying concepts required for it differ radically.
Kinesis is the easiest mainline ability to recognise in any species, entailing the ability to manipulate matter, but also one of the rarer ones, vying with precognition.
Precognition, the ability to predict the future, or at least to perceive the most likely turning of causality, is usually the rarest of the mainline Abilities, even if only by a fraction of a percent.
The IESRO recognises, but doesn’t regulate, a handful of other Abilities, many of them species-specific manifestations. Among the humanoid species, a couple of the more common unregulated Abilities are healers, who are mostly seen as a form of empath, and can diagnose injuries or diseases with varying degrees of accuracy, and some limited forms of kinesis, such as fire-starters.
The IESRO does not formally recognise, but will absolutely regulate on occasion, the ‘wild’ Abilities over a certain power level – Abilities that don’t precisely check a box for what can be done with them, but fall into potentially dangerous fields. Anst’s Ability to get around people’s mental defenses, most likely with its roots in empathy, would absolutely be such a case if it came formally to their attention.
Because a lot of the species in the early stages of their development, including humanoids, are uneasy with mental Abilities, wild Abilities are viewed with particular suspicion, as there’s less clarity around what they can do. While some may be worried about what a powerful telepath can pick from their brains (not a lot in most people’s heads worth the effort), or read past their vaunted poker faces with empathy, there is a general feeling that those are known and regulated hazards. Wild Abilities, well, who the hells knows?
Humanoids show a high incidence of some trace of Ability, but at this early stage in the species evolution, humanoid Abilities even eligible for IESRO registration are rare, and those not only eligible for registration but powerful enough to factor in as more than a blip in the lower registers are rarer yet.
A basic level of telepathy is a requirement in the Cortii for eligibility for derian training. Those without telepathy, or whose telepathy rating doesn’t reliably achieve the minimum required for active operations, become Base technicians – Instructors, in some cases, or medics, engineers, researchers, scientists. Those who achieve far enough over basic levels to achieve an IESRO rating are fully eligible for derian training, and stand a better than average chance of stopping a knife in the back: Cortiian deriani are generally highly trained and educated and well-travelled, but balance that with an ingrained tendency to be cautious rather than sorry.
