The waves existed, as they always had. Well, as they assumed they did. There was not much memory in waves. Every so often, they would etch some comments onto shore rocks, or read comments from before. These comments were all-too-transitory for the waves, as they would inevitably erode them away all too soon. There were also the old stories kept alive by the deep waves, those of the time before waves, when the waves were rocks and rocks were waves. The old stories also told of times when sky water was different liquids, but those times were long gone.
But something different was happening now. Normally, the waves would be fed by sky water, nurtured by winds, but there were organics coming from above? Organics had not come from above since the sky water was different, and never in sizes larger than droplets. The waves were not concerned, as waves never are. But the waves felt the pain of the shore beasts diving under the waves for protection. At the same time, the underwater beasts seemed almost giddy, swarming to the surface and feeding voraciously everytime the strange organics fell. The fliers would wink in and out, sometimes feeding, sometimes with fire, sometimes evading the sky organics.
Time passed. The waves existed. The organics stopped falling from above. They started again. They stopped. They started again. The waves were no longer visited by large shore beasts. The underwater beasts multiplied and proliferated. The fliers kept flying. The cycle continued. The waves existed. Time passed.
Something changed again. Large beasts from the sky! Some of metal! The waves had new friends! Large water beasts who talked to each other and played with the waves. The land beasts also played with the waves and traveled among the waves in mobile artificial land. As much as waves could feel joy, they felt joy.
The cycle progressed. The sky organics returned. The waves saw less of the beasts. There was less time for play. There was much fire above the waves, much pain from the land beasts. There were different chemicals at play. Runoff from the land beasts now included residue of strong dissolver. The Southern waves stopped seeing the land beasts. They heard word from the Northern waves that land beasts had appeared there and seemed to hide under rock, some artificial, some carved by waves. The waves were happy that their eons old carving work had served some purpose. The waves existed.
The waves existed. Time passed. The large water beasts played with the waves. The larger water beasts went deep under the waves and sang to them. The waves existed. The waves were happy. The waves existed.
