Gray Tide

When the sea swallows up the last burning sand, the last words of all the drowned become the fuel for the sound of the tide. The earth has fallen into eternal night due to "tidal imbalance syndrome" - the ocean has swallowed 99% of the land, and the survivors live in floating city-states. The only energy source that can temporarily suppress the tsunami is the "living ashes" salvaged from the seabed. These pulsating ashes are like a heart, and the blue fire they release when burning can freeze the waves for 12 hours. The cost of burning is to draw the user's memory as fuel.
