Haven't been added to mogstation as they'd need to make it a different item to do that. People are saying they're insanely expensive due to the rarity, which seems to ring true. On Aether - Siren, there is 1 listing for Starlight at 900m, Egg Harness no listings, Paramount I cannot even find on the board.
