Atalantëatani

When the fall of Númenor was foreseen by some of its wiser citizens, a small group decided to flee to the bosom of Uinen, Lady of the Sea. They sorcerously achieved to alter themselves to breath water and established a haven beneath the waters of Belegaer. Enough sightings and rumors of them had come down through the years, to produce legends of a sunken city, Vanwa Atalantë (Q. "Lost Westerfall"). In reality, they were but a small, dosed, failing community, but some still sought either revenge or forgiveness from the surface world.

They appeared as men and women of dark, stern appearance and great heighth with strangely pale complexion, cold skin and constantly radiated the smell of mildew. The Atalantatani had pretty much lost their ability to survive on land and in air for longer times, as they easily suffered from dehydration, had little tolerance for warmth and easily risked heat prostration if hiking more than a mile or so on dry land or going for four hours without immersion.They also were used to eat raw flesh ( or rather fish) and did enjoy cooked food only little.
