The Forestborn Peloran were supposed to be the Albion’s ultimate fire and forget weapon in their war against the Ennead. Someone they could send deep behind enemy lines and not worry about supporting. Most died in those long missions, which is one reason why there’re so few of them even now. Another is their low fertility rate. That’s a side effect of the plant DNA embedded in their genetic codex. They eat the light of stars to live on, but bringing new life into the worlds is so very rare for them. More rare for those who subsist only on sunlight, but even those who eat normal food have children far less often than other humans. And that is why most Forestborn Peloran are born in cloning tanks rather than the old fashioned way.
