Elemental

The Firstborn were the first race created by the Golden Goddesses. They were powerful near God-like beings that led the Trilith in wars against the demonic Druthulidi. The First Sages are the only Firstborn known by the people of Hyrule, though other such beings might exist.

Physical Characteristics
Firstborn all appear as huge beings vaguely similar in appearance to a Hylian, often composed of the base elements of which their Sagehood represents, such as Malkorbagia, Maphaeus, Kovaloo and Solahrasin. Others have an appearance distantly more similar to a Hylian, such as Sulkaris and Evaleen, who are the representations of mortal life and death respectively.

Powers
The Firstborn have incredible powers, in that each one was given a specific task by the Goddesses and they had the powers to accompany that task. These powers range from:
 * controlling the flow of time
 * manipulating light
 * the ability to give life and control it's growth
 * control fire and earth
 * control water in it's different forms e.g. ice
 * the ability to create plagues and give death to any living being
 * the ability to guide spirits to the afterlife, as well as conjure powerful winds

Dawn of Time
After the Druthulidi Majora tells others of his kind about Hyrule they begin to flock there, they then wage wars against each other to dominate the land, which lead to great death and destruction across Hyrule. In response to this the Golden Goddesses created the First Sages to enact their purging of the planet. Leading the Trilith into many battles against the numerous Demonic armies, resulting in the death of many of the Druthulidi. Once the wars ended the Sages left Hyrule to enter the Sacred Realm, so that they could guard the Triforce, a holy treasure left by the Goddesses.

Ancient Age
During the Sages rest within the Sacred Realm, Sulkaris the sage of forests attempted to steal the Triforce for her own ends but is cast out by Solahrasin. After her fall, the remaining Sages, with the exception of Demoko and Solahrasin, passed their titles to a chosen mortal and settled into anonymity among the people of Hyrule.

Malkorbagia isolated herself in Greshou Library.

Maphaeus settled deep under the caverns of Death Mountain.

Evaleen lived among the Ancient Hylians of Kakariko Village.

Kovaloo departed west with the wind, supposedly to guide the spirits of the dead to the afterlife.

Solahrasin returned to the Sacred Realm with its armies, creating a plane of existence known as the Silent Realm in which to wait until it was again needed.

Demoko returned to the Sacred Realm to guard the Triforce, and tasked the Wind Tribe with this sacred duty.

Return of Sulkaris
The Firstborn are driven into extinction by 129 AG, either killed off by Sulkaris or, in the case of Sulkaris herself, destroyed by Link wielding the Master Sword.
