 The Vondire family have secured the planet FO-Gamma (Fallout Gamma) and its native population in the last war.

 

The family plans to use their new subjects to conquer and colonise more worlds.  However in the early stages of their colonisation attempts, it is discovered that PSH genome of the FO-Gamna does not allow them to interbreed with human populations of other worlds.  The gametes of the PSH tend to kill off those of other genome rather than forming Zygotes.  This will significantly slow down colonization programmes as the Vondire family will have to ship both male and female settlers when building new colonies.

 

Gregory Vondire has been tasked to venture to the outer Realms to seek genetic manipulation technology to cure the FO-Gamma colonist of their genetic complication.
