There are Conduits who have the ability to sense bridges from farther away, or jump between worlds even if they are nowhere near any bridge. Lawrence is not one of those. But he does have Gravitic Angel, and he can accelerate his body to four gees in a moment. He typically doesn't go that fast, and if he does, he constructs an aerodynamic shell around him made of Prison marble so he doesn't burn up from air resistance. He doesn't need to see in order to see — his Spatial Sense extends 81 meters all around him and doesn't require line of sight. He sees mass density, gravity, electromagnetism.
He's exploring a new floor of the Prison today. His Duplicate in his Bevin is taking down what his original body is Spatially Sensing on a marble square, to form a scale diorama.
...there's something weird in the distance. He's looking with his eyes, not his Spatial Sense. It looks like a tear in reality, with its jagged, wavering edges. There's something on the other side, he thinks. Is it a portal? It doesn't...doesn't feel like a bridge, to him. He knows Kuiper has wormholes and hasn't experienced looking at and traversing them but he doesn't think they look like that.
He gets closer and wow, his Spatial Sense is freaking out. Energy popping in and out of existence in a very physically lawless way!
...it's definitely not a bridge because he can't use Scrying on it. But can he peer through the portal to the other side?
