Thestrals were 'welcome' in Equestria again, but little had been done to promote that. Arnon sought to change that. Immigration programs and incentives, a collaboration with the Canterlot Museum to archive a special section dedicated to Thestrals to engage the public. And, boldly, meetings with the splinter-factions, like those who wanted things to return to how they were pre-banishment, and even the Children Of Night, a splinter group who desired Nightmare Moons return.
