Hidden beneath the vicious storms of Neptune are continent-wide ice sheets and a vast and mysterious ocean. The planet is known for their dedication to the defence of the Kuiper Belt, though salacious tales of secret shrines to the same dark entities they fight persist. The glacier continents are a harsh place to live, but a rich and extravagant culture hides in the depths of her oceans, well insulated from the rest of the
Sol System.
Uranus and Neptune work together to defend the solar system against external threats. Together they create and deploying
Sentinels out into the
Kuiper Belt. The Kuiper Belt resonnates with the orbit of Neptune. Many former outer planetoids and asteroids within have been pulled into Neptutian orbit, or flung further out into the depths of the
Oort Cloud by the force of the ocean giant's gravity.
Falls
Life flourishes around the dead of Neptune, and no corpse can feed as many as the great kraken whales. The first cities of Neptune were build on and around these gargantuan corpses. The largest Falls, known as metropoles, sprawl out into vast submarine mega-cities that barely resemble their origin.
The Falls have defined life in the seas. Hunter-Colonialists tracked down and killed so many kraken whales to establish their own domains and feed the metropoles that the species verged on extinction. Modern Falls are now completely manmade, and conservation efforts aim to bring the kraken-whales back.
Song of the Seas
Sight and smell are dulled underwater, but sound travels faster and wider. The oceans are loud. A series of species known as the choir of the ocean measure the world around them, and use their bodies as instruments to communicate. They echo the song and layer on their truth. Together they weave an aural soundscape, and map out the underwater world.
The deep song travels far and wide, pinpointing the locations of the Falls and the kraken whales, and bouncing off the ice sheets. The Falls sing out to eachother like their live brethren too, the corpses orchestrated by sonar conductors.
The more populated seas boast a denser and richer band of frequencies. Most members of the choir sing to echolocate or communicate with their immediate area, and higher frequencies and clicks don't travel as far as the deep song.
There's so many interesting things I want to learn more about here. I especially like the use of kraken whale falls as the basis for civilsations to grow from. :D

Thank you! It's got me looking forward to when we return to Neptune and can go more in-depth too. I was thinking about our own oceans and what I would like to bring forward in Solaris, and I just adore whales and whalefalls as an ecosystem of their own. Turning them into cities just felt right.
