For the most part, their role doesn't distinctively involve challenging the Lords of the Nine; Barachiel oversees the defense of the first layer against incursion; Erathaol predicts major planar events; Raziel would be the vanguard general of Celestia if there was a need to lead a force off-plane for any reason; and Sealtiel ensures that the highest layer is protected from any unworthy beings attempting to enter.
Chauntea remembers herself in all aspects, she just considers herself more complete now. Aspects of Chauntea are worshiped in many lands under many names and with many attributes, though they are not independent deities. Certain principles and precepts remain central to Chauntea specifically and not other deities; for instance, she has never been a goddess of the hunt, and so veneration of the hunt would go to Malar, not Chauntea. She is not goddess of the woodlands; veneration of the forest's bounty would go to Mielikki.
