"Álàntúr City" by Fyrius (Fery Camillus)

This is an underwater Álàntúr city on the Ocean World. Every orb is a building, and every tube is a tunnel that connects those buildings. There is also one spherical wall around the entire city, to protect the buildings from strong currents and waves of extremely hot or cold water.
The Ocean World is a tiny planet with a huge ocean all around it, or rather just a huge cloud of water with a tiny planet in it. The mass of the planet is just enough to create a gravity field that keeps all the water around it. This vast ocean is home to the Álàntúr, a race of intelligent aquatic snake-like beings with highly developed psionic powers. See the two pictures of Álàntúr (version two) in the gallery about what they look like.

Anyone who paid close attention to the rest of my gallery, if such people exist, might get confused now. But in Dreamworld, the Álàntúr are an actual species, rather than a Fyrian myth. They're not the same, they only look alike in appearance and powers. The name Álàntúr is a name that Fyrian travellers gave them, because the Álàntúr themselves communicate by telepathy and therefore do not use pronouncable names.
