A sudden collision between your left shoulder and an aquamarine pathway stops the line of thought dead in its tracks. The ramp of stone shatters under your obscene momentum, sending chunks of broken rock scattering in every direction. Fortunately at least the sound and shrapnel are both blunted by being underwater. It still hurts though.
Ouch.
Fortunately, the impact also serves to sharply decrease your sinking speed, meaning when you strike the next road a moment later, it merely cracks in half. You strike the third bridge even lighter, only chipping away a small bit of material and finally coming to stop.
Spirits above. It's done. How long was I… three hundred and nine divided by… ah. I was falling for six minutes plus nine seconds. For distance… I couldn't measure the speed exactly, but it felt was slower than going through the air… I think.
