The Alternian government and the governments of Earth thank you for receiving the offspring of the Mother Grub into your care. When Alternia was still a viable planet, our children were raised by lusii, creatures of magnificent strength, who helped our children grow into the trolls they were destined to be. Now that we are no longer on Alternia, we must rely on your hospitality to help our children grow up healthy and strong. We of Alternia recognize that you are taking on a great responsibility, and we sincerely hope that this experience will be rewarding for all of you.
-- The Raising of Alternian Young: A New Caregiver’s Guide.
The call for human host families to help raise the first generation of Alternian grubs on Earth had gone out a full two years before they were truly needed; before the mother grub had laid her eggs. This turned out to be a good decision. There were very few lusii left, and the ones that were alive were generally small, and would not be able to raise the trolls alone in a world that was not accommodating to them. And the adult trolls who were not jade-blooded had no clue how to care for grubs or children, having never had to do so.
The adoption committee consisted of six trolls including a jade-blood, and three humans, specialists in child and adolescent development, who would help evaluate the human families for the trolls.
Of course, trolls have different ideas of what makes a good family than humans do. There are arguments that the humans don’t understand, that devolve from broken English to Alternian, arguing in growls and clicks. The jade-blood tries to auspicsticise between several factions in the troll delegation, with varying degrees of success.
The arguments about hemospectrum are largely lost on the humans, though the trolls are adamant that their culture be respected and maintained. In the end, as long as there are no blatant signs of high-blooded favoritism, the humans allow for the trolls to have the final say.
By the time the committee has host families lined up, the grubs are nearly ready to lose their vestigial legs. Only a few lusii are left, and only three out of the entire population have found grubs to latch on to.
There are several population clusters of trolls, mostly in the United States and Canada. Most of those clusters are coastal, so as to accommodate the seadwelling trolls and not spread out the population too thinly through the country.
So...these particular trolls are...
...wait for it...
