This first chart was the original abilities chart, and represents one possible layout for mapping psi ability spectrums, and using nerve clusters. Abilities high on the spectrum will be more likely to be active from the outset, be quite easy to develop, and may be used innately, whereas those low on the spectrum will usually need to be learned (if they can be), and will generally be difficult to develop.
This chart is the current chart, which we feel is likely to be more accurate in terms of nerve cluster use. If you have difficulty understanding the terms used in these charts, please refer to the Glossary.
