Coral is a type of aquatic rocklike structure, formed from the bones of tiny sac-animals, that comes in many different varieties.
In Sload society, it is prominently used in their architecture. Dense corals supposedly provide the entire foundation of Thras and the Coral Tower itself was made from blood-red coral before its collapse. The Sload are also said to use tangled nests of coral formations to move around, and it's even used in their armorsmithing, with different types of corals providing different advantages in battle, such as lightness or durability.
Some of the most ancient ruins of Summerset Isle are thought to have been built by the Sload and are made of coral, including the original architecture of Cloudrest. In Morrowind there is a naturally-occurring bioluminescent, and possibly sentient, coral species that grows on the lands around the Inner Sea.
According to the Augur of the Obscure, coral ghosts are horrifying to behold and are said to resemble old cheese. However, the Augur was regarded by the Psijic Order as a notorious liar when it was not being asked a direct question.
Antler Coral (also known as Ocean Antler Coral) is a type of underwater coral, not to be confused with the rarer terrestrial Land Coral. The Coral Tower of Coldharbour appears to have been partly reconstructed from Antler Coral which was transported to the realm from Thras.
Summerset coral is petrified and found close to bodies of water. It can be bioluminescent.
Land Coral (sometimes Land-Coral) is a bizarre, bioluminescent, and possibly sentient coral variety that grows on land. They can only very rarely be found along the Inner Sea of both mainland Morrowind and Vvardenfell. They only come shaped as Antler Coral and the tips of the coral give off a natural fire-like bioluminescent glow. Land Coral can come in a variety of sizes and has the potential to grow large enough to tower above the landscape. It can be used to make snorkels, an apparatus for breathing underwater.
Mind Trap Coral
A mysterious coral believed to be an import from the Thrassian archipelago, it is often seen in Sea Sload mindscapes. It appears very similar to petrified Summerset coral, but has a more lively purple tint.
Spiral Skein Coral
In the Spiral Skein of Mephala, coral comes in at least two known types. The Brittle-Vein coral thrives on the remains of people who fell victim to the spiders from the realm, and the Spiral Skein Elkhorn coral gives off a welcoming bioluminescence that the spiders use to lure victims into their webs.
