Host and seed

In the case of a geneva, there is always a host, and there is always a seed.  Neither is complete without the other.   A genetic seed embedded into the DNA of host subjects reveals an astonishing array of potential psionic abilities.   The seed Is simply the key that springs the lock of genetic potential in the host.  Reality becomes permeable in various forms for the resulting geneva.   They are shown to be able to alter reality at their wills.  It is more then just a genetic tweak as the human subject grows into another species together, evolving to an alien genetic code as time goes on.  Unlocking the psionic potential of human beings has proved dangerous, with serious repercussions.  And why we pursue this path is uncertain; all we know is that geneva have had a connection with humanity dating back to Ancient Earth times.
