The Spire
A haven for everyone
Geological formation
The Spire is, as its name suggests, a giant spike coming from the very depth of the oceans. It has the shape of a cone, though would make the base unfathomably wide. It is a lonely oddity, as it is the sole unmoving thing in the Expanse. At least, it is thought to be immobile, but it is hard to tell for sure. Anyhow, the Spire is used as a universal seamark, considered the central point of the Expanse.
It is made of a strange material, as sturdy as a Sphere's shell, but at the same time it is almost like it is not made out of a single block and its lack of signature is too disturbing, to say the least. This material, called rock, interferes with the natural resonance of the water, its multiple asperities deviating the waves and creating interference or amplification patterns. It is very easy to find the Spire since one has to track back to the origin of troubled waters. This phenomenon is often mistakenly thought to be the signature of the Spire, occulting the upsetting fact that it has none.
The Spire is mostly hollow, crossed by many galleries and tunnels. Contrary to the shell of a Sphere, it is not possible to dig efficiently rock, as it is far more resistant and comes only a small chunk at a time. Hence, the network that has nothing to envy from a shell is completely natural. It comes with a fair share of disadvantages, as it is not designed to answer needs. Many passageways are too tight to allow crossing, and others are simply dead ends where some species find themselves to be unable to turn back and die of starvation, stuck in the dark rock. Navigating without a guide in this maze has proven to be a terrible mistake for more than a fool.
Life inside would normally be impossible, as no Sphere is there to provide the precious medium required for most species to survive. The owners of the place are one of the few able to stay outside a Sphere for an extended period of time, thus they are not troubled by the lack of this medium. They care, however, for their visitors, and managed through an odd mix of different arcanes, to seal off water taken from inside a Sphere's membrane to recreate artificially the living condition of a Sphere. However, this is not perfect, and they must replenish regularly their stock.
The Great Hub
Klklakk Consortium
As far as Memories go, the Spire has always been under the control of the Klklakk, a powerful consortium. Its members are huge crabs, varying in size from an Oblogg's arm to warriors bigger than rays. Even though they make the most fearsome warriors of the Expanse, they are deeply pacifist. Their collective mind despises violence and their terrible pincers are mainly just for show or intimidation. Even amongst the consortiums, they are an odd bunch. Their welcoming manners towards other species and the higher individuality of their members on average set them apart. Klklakks are for the most part able to communicate on their own, without relaying the voice of the consortium, and the few warmongers are even allowed to leave the Spire and offer their services as mercenaries or bodyguards.
In the Spire, they regulate everything. The place is theirs, after all. Every entry is guarded by a strong specimen, it is near impossible to sneak one's way in. Not that it would be necessary, as the Klklakk does not restrict the entry to anyone, except previously banned troublemakers. What the guards do is mostly verify that no weapon enters their stronghold. They care deeply about their principle of non-violence and refuse that any tool of harm is introduced inside. Nobody opposes them anymore, as their shell can't be pierced by conventional weapons and it is never a good idea to enrage the forever neutral party.
Theories around the Spire
How deep goes the Spire? Since a factual answer is impossible to find, some hypotheses have emerged.
The Dual Spire
Some say that at some point, the base ceases its growth, and begins to thin in a symmetrical way. Then, depending on who is asked, the other half emerges on the other side of the Expanse, or rest on the Abyss floor in a precarious balance. The first idea is far more unsettling, as it would mean the bottom of the ocean is the base of the Spire, and the water revolves around it almost like a Sphere on its own.
The Spine
Believers of the Father Ocean claim that this is no spire, but a divine Spine of the body of their god. To them, up to sixteen formations could exist, and at the end the godly head.
Although these are the main theories, they suffer from a fatal flaw : both affirm the existence of multiple spires, but so far only one has been acknowledged. As a matter of fact, no other formation from the Abyss seems to exist.
Fascinating place! It makes sense that crabs would be the one owning it. Is there any algae or anemone naturally growing on the Spire? Or did they all died out before the crabs took control of it and put the special water in place? do the crabs have some farms or do they buy food from the Spheres? Now, if these are the only rocks anyone has ever been confronted to, that must mean the water level has increase a lot! the humans must all live on ships - though people only know about the clouds and they haven't mentioned ships... Unless the people live on the clouds? This makes me think of the film Waterworld XD And the water seems to be deoxygenated apart from the layers near the surface... I'm really curious about what happened to make it that way, since if I remember correctly there was some kind of cataclysm that transform the expanse... Unless the theories are correct and the whole planet is only made of water with that gigantic spire going from one way to the other - though people would have found another Spire on the opposite side if that was the case... Have they even explore the whole of the Expanse, or do they stay relatively close to the Spire? A whole planet of water with no landmark at all is very vast...
Thanks! On the outside, the Spire is completely bare, though some anemones grow inside. However, they are imported invasive species, not natives. If you ask the consortium about it, they would say there was nothing but rocks as far as their collective memory goes. Now those are pretty good assumptions! Except something is a bit off, but I won't spoil what :p Funnily enough, they wonder the same thing. If the only fixed landmark is the Spire, it is very difficult to say if they explored everything. Even the area most of the Spheres are found is of unknown size, relative to the planet. Explorers often set sails toward the unknown and go straight. Sometimes they come back on the opposite side of the zone, but mostly they are never to be seen again. The only thing they can conclude if they trust the explorers is that the Expanse is somewhat circular and has no other rocky formation on the explored paths. Maybe they never came close to another Spire, and the planet is way bigger than what they know, or on the contrary very small..
