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. The Prison could be described as a flat expanse with random polyhedra and shapes jutting out of it. But jutting out is the core part. From what he's seen, the Prison has a set floor that it tries to move raised parts to — it is very slow, on the order of decades or centuries, but he's been a Conduit for fifteen years — but nothing goes down into the marble aside from the spiral staircases that connect each floor.
He flies closer. It looks like, holes? Jagged holes, pretty deep ones. He moves closer...yep. There's a bridge here. Not to a world he's connected to. It feels...dark and menacing? But not in the way Yomi is, from what he's read of Yomi...
Fortunately, he doesn't have to go in blind. He activates Scrying. What does he see on the other side? He can move the point of view, and he will, but it's slow, at around a walking pace.
