Cosmic / Light / Shadow will be public, yeah. While cosmic does have a lot of lore behind it, I feel like the vast majority of players are good with that and since it's neutral in alignment there's a lot of leeway in how they roleplay it. So long as they're aware that it's siphoning mana from a star compared to say, Energy, which is raw internal mana, we're good. I wouldn't put it under the same category as Holy / Occult which has higher expectations in terms of character behaviour.
