|“||“Then I stood still, forgetting war in Middle-Earth; for their wailing voices spoke to me of the Sea. The Sea! Alas! I have not yet beheld it. But deep in the hearts of all my kindred lies the sea-longing, which is perilous to stir. Alas! for the gulls. No peace shall I have again under beech or under elm.”||”|
–-Legolas, The Return of the King, The Last Debate
The Sea is an extremely large biome surrounding Middle-Earth and is, as the name suggests, an ocean. This biome represents Belegaer, the Sundering Seas, the great western ocean of Arda. It surrounds all of Middle Earth, and is infinite.
It is mostly entirely made of water, and only squid spawn there, but there are islands that may contain mobs in the future. These islands are barren, with the exception of small Númenórean ruins scattered around. The colour of the water in the ocean will change depending on the player's latitude. Ice will also start forming as the player travels far north.
Upon reaching this vast body of water the player gains the achievement "To the Sea!" and the title of Mariner.
The sea has two sub-biomes.
These islands are randomly generated in the sea as well as in specific locations, representing specific islands. No people are known to currently inhabit these islands, although at a time they were part of Beleriand. oak, birch and beech trees dominate the flora.
This biome generates where the sea meets the land. It's mostly sand. Most of Middle-earth's coastlines consist of this biome, although there are also some rocky coastlines. There is also a white beach variant, made of white sand and a gravel beach.
One structure spawns in the sea, and one on the islands.
- Underwater Elven Ruin- These ruins are composed of Elven brick, with some glowstone and a chest, containing valuable loot. Despite the risk it would take to dive down, the reward is often worth it, as these ruins have been known to contain mithril.
- Númenórean Ruin (Middle-Earth islands only) - Dilapidated towers of stone brick, remnants of Numenorean colonies. They are hollow and often contain a single tree.
No sentient creatures inhabit the oceans and islands. The waters are alive and host many shoals of squid and Fish.
The Islands are known to host many types of non-domesticated common animal wildlife, survivors of ages past. Notably there is no Rabbit, Bird or Butterfly of any kind. The abundant presence of seagulls may explain this.
The underground of oceans and seas contains two and a half times as much rock salt as any other biome of Middle-earth. In the sands and soils of oceanic islands and shores, up to elevation levels 80, there is an additional small chance to also hit rock salt deposits.
