Strains

In the world of The Citadel, there are only two boundaries that are defined at birth; who your family is, and what your strain is. You can leave your family, finding another Tribe in the Outlook, but you cannot choose your strain. There are two strains in this setting, the dead-strains, who appear like modern-day humans and show aptitude with technology, especially the AI, and the gene-strains, who have the capacity to mutate, and who have discovered the power of Psionics.

Dead-Strains

Dead-strains have mutated into a “stable” state. They cannot be Psionicists, but can be involved in the Communions of Psionicists. They cannot mutate in play. Gene-strains have mutated, they are unstable; they can mutate into different forms. They cannot be Technopaths; although AIs dislike them, they can have AIs bound into their “ka”.

Dead-strains are “humans”. They appear recognisably and completely of the human genus, although their clothing reflects the tough times they live in. Due to their appearance matching those of ancestral humans, and their heredity being similar to them too, they have a closer relationship with AI than that of the gene-strains. This includes the power to control the potential of their hereditary genes, and learn the secrets of Techgnosis. Their closeness to their ancestors also leads to their ka being more receptive to AI, meaning that they can house more AIs than Gene-strains.

Gene-Strains

Gene-strains are “mutants”. They appear to diverge from the modern human genus by some margin, expressing anomalous details such as scales, fur, antlers, markings, oddly coloured skin, or even tails. Thanks to their physical and hereditary divergence from their ancestors, they are distrusted by AIs, and ancient devices do not recognise them as human. However, their divergence has also led to them expressing new powers. Using the forces that cause these mutations, they can enact changes upon the world with focus and will.

Gene-strain humans vary greatly in appearance; some are at first glance indistinguishable from dead-strain humans. AI are able to tell the difference with minimal interaction. As mutation effects are limited by “active” mutations, it is possible to possess cosmetic mutations that provide no active benefit. However, these mutations should never be complete, to the stage one looks like an anthropomorphic animal- they should be more patchy in nature.

It is inappropriate to use metallic colours as a Gene-strain; this is supposed to emphasise the “organic” nature of the mutations.
