I was lucky. I managed to catch myself in the swift-moving waterfall several blocks below my platform.
The spirit of the water - welcomed me. I can't explain it any better than that - it sensed me, and I sensed it. I felt its movements, and it showed me how to move with it, even climbing against the current.
So, slowly, I climbed back up onto my platform, through the waterfall itself, soaked thoroughly, but alive.
The water spirit was disappointed, I think, that I had left it.
For my part, however, I knew that what I had just done was completely impossible without magic - in my world.
But, as I said before, gravity seems to be entirely arbitrary here. With nothing more than the screaming terror of the void below me - well.
All I knew then was that I did not want to fall into that gaping abyss. I knew, without knowing how, that it was death.
I sometimes wish for that early innocence.
The things I know now ....
