Maia

Maia are lesser beings gifted with great power from, or directly created by Valar. They are in some cases considered godlike, (Or demigods) but their powers are limited.

Queen Gladmir, the last immortal
Sometime in the first age, Queen Gladmir reigned over the Elven race. Helping them to cobble their culture's together under the new rules of death that now applied to them. Gladmir for a time was able to keep all the elves of the world united, until she mysteriously disappeared and a new monarch took her place, in the year 2345 of the First age. This was the event that split the elves into many factions, as new generations of elves whom had never seen the light of the creator Aen refused to follow a false ruler. It is believed that Gladmir was the last of her kind to keep her immortality as a gift from the Valar and therefore that she must still exist somewhere. But she was never again seen.

Samuel The Righteous
The First man to be accepted by Dwarven culture and to adopt faith in their creator, serving as a Paladin. He was gifted with ascension when he achieved great things and tasked to watch over the humans under Dwarven protection.

Kong The First King
Southern tails tell of an ape gifted with sentience and tasked by a greater power to teach and Shepard his new race. Kong was a masterful warrior and in the tails he was told to be the first human, possibly in the first age. He is said to have achieved an ascendance beyond that of mortals. If these tails are true then humans would have been first seen in the far Southern expanses of land before they migrated and expanded their kingdoms.
