The Supremos Manus Dei.
"The Supreme Hand of God. Your horrible naming sense transcends the multiverse, Bernard."
[I am not done explaining.]
Supremos Manus Dei—a device that amplifies the intricate invisible waves that Alice produces whenever she actively uses her telekinesis. For a thing that has been addressed as a 'device' ever since Riley had been hearing of it, he was expecting something small; like a futuristic crown that scans his brain, but no.
The device was an entire spherical room, completely filled with some sort of gel that Riley could somehow breathe through. Bernard explained that it wasn't actually gel, but more than a hundred quadrillion translucent nanites that served as some sort of conductor for Alice's telekinetic abilities.
