The Autrobulan Ambassadorial Corps was a network of Autrobulan caretakers for the Autrobulus hive. The caretakers lived and worked in facilities on the surface of the Beshielach, though the hive made it clear that they'd tolerate no damage. It was considerable time before any Beshielach acted on this threat, though that Beshielach was later exonerated. (PROSE: The Book of the War)
