There are a lot of Amentan countries. Vanda Nossëo representatives are dispatched to all of them. These Elves (two with black hair, one with silver) take a shuttle down from the lightleaper to a country called Calado, and radio ahead to request permission to land at a elegant modern spaceport.
And he reaches out to some demons who do terraforming and ask what they could do with an appropriate variety of planets at the right distance from their suns in Revelation.
Shuttles pop about between Amentan countries and their shiny new colony planets, which are mostly land except for near the equator. Shuttles to Elendil are every ten minutes in most places. Bus guy gets a bigger bus.
Companies hire local consultants on the hair color thing and publish hiring listings which observe that local nondiscrimination law prohibits taking into consideration factors such as caste, ethnic group, religion or national origin in hiring. But for the convenience of Amentans, jobs can be sorted by the Amentan caste with which that sort of work would traditionally be associated.
Ambassadorial and diplomatic work, trade negotiations, infrastructure development (especially seeking local consultants who could work with a municipality to develop functional public transit), serving on oversight councils in polities that have merited extra oversight recently for some reason...Portal research, wizardry research, new planet research, magic music development, lecturer position at these hundred universities scattered across sixty-two planets...compliance monitoring, prioritization monitoring and management, artifact design, policy and trade and taxation and allocation work...internal security, investigative work, rapid response teams in dangerous situations...healing, teaching pre-industrial aliens medicine, divine magic research and manufacture work, social workers, community outreach work, counselors, child support services...magic item manufacture, shuttle transit, aid shipments and delivery and distribution, teaching pre-industrial aliens construction and manufacturing and infrastructure and electrical work...
The hiring manager for the oversight councils thing has silvery fur and a bone spur on the top of his skull that flushes pink when he's worked up and barely seems to register whether the people in the room have Amentan-traditional hair colors. "All right, I read all your applications and you're here because they looked great, except those of you who speak Valtaz should know that the grammar came through kooky and someone should twiddle with your Allspeak settings. Welcome to oversight and monitoring. We have half a million employees, we work in six hundred different polities, and our job is to ensure that every single election, every single state use-of-force incident, every single violation of membership terms and every single complaint are meticulously and transparently monitored, evaluated appropriately, and escalated whenever that's warranted. You with the lavender hair, do you have a question."
"First four months in a new place you're shadowing someone who's been there a while. Average length on an assignment is six standard years but that's misleading, most people either request a transfer before training is out or they stay a real while. People transfer for culture fit, mostly, though there are a few places we have trouble staffing because of the weather."
Amentans get assigned to shadow observers. Amentans get taught magic (which won't work on their colony planets, the hiring alien explains with annoyance, it's in the next dimension over.) Amentans can trade in more conventional goods. Amentans can get tourists once agreements for that are negotiated (everyone else feels very strongly that Amentans had better not execute random tourists for drunkenly peeing on the side of a building or something.)
