function TransformHavenTown(_, _, hero)
	if hero == "Pelt" then
		TransformTown("scripted town name", TOWN_NECROMANCY) -- transform the town into a Necromancy town
		sleep(10) -- pause for 2 seconds
		SetObjectPosition("Pelt", GetObjectPosition("scripted town name")) -- move the hero to the town's coordinates (if the garrison is free, the hero will be placed there)
	end
end

startThread(InitBuildings) -- start the function in a new thread; return values are ignored; does not wait for the function to complete
Trigger(5, "scripted town name", "TransformHavenTown")
