First post; d10 floating sea villages

Beginnings are delicate things. Honestly I don’t like them so let’s skip to the part where I am blogging about table-top role playing games, okay?  But maybe one more thing before we get started: writing for the internet is unforgiving, and so I ain’t gonna do it.  I am writing this for me (and maybe you, if you like it). My brain is full of random dreams, whirling around in a roaring kaleidoscope.  It’s time to pin some of them down.  Here.  

d10 floating sea villages

1. The village lies in a dense Sargasso Sea, where masses of algae are walkable in parts, a shifting “land” to live in. Algae are oily and magical algae could have all sorts of useful properties.  
2. The villagers live in dead, inflated giant octopus corpses, treated with special algae to make them not rot. 
3. Each village lives on the back of a great dragon turtle, which requires regular animal sacrifices from the villages' herd of tame manatees. And sometimes the turtles mate, causing a ruckus. 
4. The villagers live on linked rafts built from dragon bones, which happen to float and never decay or break. Many of the bones are thousands of years old, and finding a new one on the waves is a major stroke of fortune. The rafts of bones are tied together with magic algae, making them sturdy enough to withstand hurricanes and angry kraken. 
5. The villagers walk on water in special shoes and build on water in ball-like nest-tents made of fey duck feathers. Their tents never sink and they keep the sharks out. Each winter they harvest thousands of ducks from the annual migration. 
6. The villagers live in a part of the ocean with really heavy water, like corn starch. A great spell gone awry created water that one can stand on, provided one never sits still. There are no storms but the water is dark and clouded, making only fishing by fixed traps and nets possible. Sea life there is strange. Each house sled is drawn by a team of manta rays, and if they stop pulling, the house starts to sink. Needless to say they sleep in shifts. 
7. The villager’s island has become unmoored, dragging along the bottom of the ocean. Soon it will fall into the abyss, if nothing is done. How could this have happened?  
8. The villager’s island is floating because of magic, obviously. Just as obviously, that magic is failing or on a timer.  Maybe the magic is evil. Maybe your group caused it.  Either way, unless something is done soon, the waves will cover all.  
9. The villagers are nomadic traders, and the village is a collection of impressive seacraft made from various megaflora and megafauna.  They meet several times a year to bargain, party, and unite their clans in song.  Giant bamboo outrigger rafts anyone? 
10. The village floats to a new island, once a new moon.  It happens in a dense fog at night, and anyone who goes out of their house at that time falls into the sea.  The villagers want regular lives and to lift the wandering curse, but what caused it?
