Weren't the Celestial's traditionally portrayed as organic or at least semi-organic in nature? If remember correctly inside of Exitar were Thor-sized organisms that acted as his immune system. Now I see in Guardians of the Galaxy #1 Knowhere is housed iside of a severed celestial head that has conduit and other "robot"-like wires coming out of the neck....did they change what celectials consist of or have I always thought wrong about what they were made of?
