Not sure what to insert into the: Control Panel with a Unique Slot.

[Hystorm]

This is in the: 'Secret Chamber' of the Githyanki.
I would take a screen shot but its not working for some reason.
Around this center platform are whats called: Lathander Solar Machines, if that helps.
When you click on the center item labeled: Control Panel with a Unique Slot, it opens a window where I can put something in it.
No clue what to use here. Can anyone give me help on this?

Thanks in advance.
