Yuri follows them into the mine, once again going very silent, her steps fading into nothingness within the mines.
Around the same time as Ghost thinks to search for magic around them, she extends her blood-radar to attempt to find the source of the voices, though she's not exactly certain it will work (Your call whether this needs a roll, Scap, since it's technically a passive.)
As they enter the chamber with the pair of fighters, she hangs back some, recognizing that she would not be much help in a fight, and this would not be the time to release Demons Run to help if things got hairy. For the most part, she spends her time thinking, contemplating just how she could go about questioning the pair before she realizes that she had completely forgotten about the bracelet she'd been given, absentmindedly snapping it onto her wrist.
And through the connections of arcane thought, images rush into her companions' minds. Images of a boy, most of his body covered, but for eyes and hair like a starry night sky. Images of a girl, pale of hair and silver of eye, her whole body suffused with radiance and power. Images of time, of space, of the past, and the future, pouring through their minds eyes... Even images of Matt in his hidaway, glimpsed long ago.
Yuri falls to her knees, groaning and taking hold of her head, barely managing to stabilize the connection within a few moments.
