You guys are a little too fixated with umbral and astral stuff when it's not that relevant for most things. And Shadowbringer already proven Astral is stasis, and umbral is active. You don't have to switch terminologies, nothing has changed in the Source from that expansion. Astral is still light oriented coded with bright colors and umbral is still darkness oriented coded with dark or sinister colors. There's still dark crystal and light crystal enemies and such in roulettes, they're not suddenly each other's existence. The world knowledge had mostly operated on light vs darkness nonsense anyway. The most relevant thing about calamities we know of is that the 7th calamity is intense umbral energies of probably all six elements, and the The First's calamity is intense astral of all six elements
