Anyone also notice the Haragon in that Silver Dragon art? Makes me wonder if their solution to the Ardlings identity issues was to split it in two, the papa Aasimar for the celestial aspect, and mama beastkin for the Furry species, then take a bunch of furry races like Haragon, Tortles, etc..., and turn them into lineages.
Anyways a reminder of what the OG Ardling's Celestial Legacy was like:
" Exalted. The fierce passions of Arborea, the heroic heart of Ysgard, and the wondrous nature of the Beastlands call to ardlings who have the Exalted celestial legacy. Their celestial ancestors are heroic champions of the Chaotic Good planes. (Gain Thaumaturgy, 3rd level Divine Favour, 5th Lesser Restoration)
Heavenly. The blissful harmony of Arcadia, the unwavering justice of Mount Celestia, and the bucolic paradise of Bytopia touch the souls of ardlings who have the Heavenly celestial legacy. Their celestial ancestors are staunch defenders of the Lawful Good planes. (Light, 3rd Cure Wounds, 5th Zone of Truth)
Idyllic. The Idyllic celestial legacy connects ardlings not only to the Beastlands and Bytopia but also to the eternal compassion of Elysium. Their celestial ancestors are paragons of kindness who hail from the Neutral Good planes. (Guidiance, 3rd Healing Word, 5th Animal Messanger)" The animal stuff does not apply to the Aasimar.
They might add a resistance to each of these, Lightening to Exalted, Acid to Heavenly, and Cold to Idyllic.
They might dump Angelic Flight for Darkvision, not sure, but I think they will keep the Radiant Resistance univeral.
