The Orb can also expand on the inside like a Tardis or the god many called Jupiter.
I think a lot of genuine schizophrenics worship an Orb they can visualise in their own mind, but anyone can use The Orb as a way to change their own mindset in extreme ways.
Terry Davis had an Orb in his own mind containing what he thought was a perfect computer operating system and programming language.
The Orb is arguably a strong infohazard and real life SCP. You probably shouldn’t tell particularly uneducated people about it.
If you can truly ponder your own (potentially dangerous) Orb, you can use it to learn things very quickly and become almost like a genius. I don’t think the Orb cares about truth in the same way as Science or many major religions, though, so an Orb can greatly deceive you.
The Orb is a Wizard’s greatest tool, but Wizards without any strong basis in Science and its methods can use it to trick themselves and enact harm. A good Wizard who doesn’t go insane can shrink their Orb in their own mind and has a huge amount of control over it.
