As it looks like the plan is set, the wizard will finish the ritual. He will think more loudly than usual.
~EVERYONE. THIS IS NOT SOUND. IT IS A THOUGHT I AM PROJECTING INTO YOUR MINDS~
Now that he has their attention.
~We are telepathically linked. You can project your thoughts and receive projections to and from everyone here. I recommend you practice it.~
~Once you have some control, you can decide which thoughts stay with you, and which others hear, so to speak. You do not have to see them, they may even be some great distance away, and you may still communicate.~Assuming no planar travel.
~Do not fret. We--I--cannot read your minds~ Well mostly cannot. You never know what will slip.
"We can of course still speak." He says. "Better to do if you want the giants or someone not linked to hear."
He puts his book away.
