Amaurotines were approximately three times the height of a Hyur, much taller than all the Eorzean races, implicitly because of the difference in aetheric density compared to the modern-day races of mankind. In-game models appear to mostly use facial features belonging to Hyur and Elezen, but the reason for this is unknown. The eye colors (in the rare times an Amaurotine is seen without a mask) were also notably more vibrant, likely as a visual shorthand to express their aetheric density.
Available information also tells us that like modern mankind, the lives of the Amaurotine were not infinite, though the exact bounds and conditions of maintenance are still somewhat unclear. Children were "born" but it's not known if Amaurotines experienced pregnancy, if two parents of opposing sex were required for it to happen, or if there were limitations on who could birth a child as there are for modern mankind. Children aged into adults, and adults showed visual signs of aging. Death, or "returning to the star" as the Amaurotine prefered to describe it, is implied to be a predominantly voluntary action that is chosen by Amaurotine who have lived their lives to the fullest. Outside of this choice, premature death did seem to be possible if caused by injury, and possibly if the Amaurotine failed to fulfill its basic needs.
Amaurotines all traditionally wore identical robes and half-masks, as expressions of personal identity were considered rude and unseemly. The color of the robe an Amaurotine wears also had significance related to their societal role. Specifically, white robes are meant to indicate that the individual wearing them is capable of serving as a "neutral advisor" who can assist other Amaurotine with conflict resolution.  It is yet unclear how an Amaurotine earns these robes, outside of being a member of the Convocation of Fourteen.
Though little consistency is found, most Amaurotine are named in ancient Greek or Latin after figures from real-world mythology and legend, such as heroes, philosophers, or gods/demi-gods.
Before recorded history, the Ancients were the only beings that inhabited the star. The Ancients were able to wield Creation magic, which they used to build a glorious utopia. The citizens were able to dedicate themselves to their principals of rhetoric, creation and public service. These beings were ruled over by the Convocation of the Fourteen, who were the wisest and able to use Creation magic to the fullest.
But one day, something creating a sound that disrupted the use of their Creation magic echoed from within the star, causing the birth of malformed creatures formed from the Ancients' deepest fears. Because their magic was corrupted, they were unable to bring the creatures under control. This caused the people to further despair, creating more monsters and causing more chaos. This time of destruction came to be known as the "Final Days".
Realizing they had little chance to bring the chaos under control, the Convocation sought to rewrite the laws of reality of the star. To achieve this, the Convocation sought to summon Zodiark, a being of immeasurable power. However, the cost to call this being forward was great, requiring the life force of half the Ancients still alive to amass the amount of Aether required. Opposing this, the Ancient named Azem left her position on the council, not wishing to take part in the senseless loss of life.
And so, the Convocation sacrificed half of the Ancients to summon Zodiark, with Elidibus acting as the ancient Primal's heart. Zodiark was able to prevent the total destruction of the star, however the Final Days had rendered the planet a destroyed, lifeless place.
The Convocation sought to use Zodiark's power once again to restore their home to its former glory, however there were Ancients who opposed this idea, not viewing using the primal's power as worth the cost. This group of Ancients were led by Venat, arguing that the loss of life to bring back those who were previously sacrificed to summon the primal the first time was foolish.
From this conflict, the Ancients under Venat sacrificed themselves to summon Hydaelyn, with Venat acting as its heart. They used this primal to seal Zodiark and lock his powers.
The two primals were locked in an eternal conflict, destroying what little life was left on the star. This continued until Hydaelyn struck Zodiark down with all her might, shattering the very fabric of reality, splitting off thirteen reflections later called Shards. This also split the souls of the remaining Ancients across the shards as well. This came to be known as the Sundering.
Elidibus, Emet-Selch and Lahabrea managed to survive the Sundering. But seeing the damage caused by the battle between Hydaelyn and Zodiark, they came together and vowed to restore the world and the Ancients to what they were before the Final Days. They set about finding the souls of the other members of the Convocation to bring them together once again, and planned to use the newly created life forms to summon Zodiark to Rejoin the shards back to the Source and unsunder the souls of their people.
After gathering the members of the Convocation together, the group reunited under the name of Ascians, and set off to each of the Shards to bring about large enough Calamities to force the Shards to rejoin the Source.
Each Shard was to be overseen by an Ascian. However, this changed after Igeyorhm accidentally led the heroes of the Thirteenth to being exposed to the corrupted Aether of Primals trapped within Auracite. This caused the people of the Thirteenth to go mad and attack one another, bringing about the Calamity of Darkness, turning the Thirteenth Shard into the Void. From here, the Ascians worked in groups to bring Calamities to each Shard. Notable examples of the Ascians influencing events in history are Emet-Selch starting the Garlean Empire or Elidibus becoming the first Warrior of Light in history.
Throughout the Source's history, The Ascians have worked to sow chaos and destruction. By creating a Calamity on a Shard and a corresponding Calamity on the Source, the Shard will rejoin to the Source. So they set about sharing their Creation magic with the people to teach them to summon Primals. THe first time this can be seen on the Source is when the Meracydians summoned Bahamut against the Allagan Empire.
- Interaction dialogue from Eloquent Amaurotine (x18.9, y26.8 The Macarenses Angle/The Tempest) "Oh, do you hail from another city originally? Even so, surely you must know you stand in Amaurot, the intellectual utopia that flourishes at the heart of our world.From the Capitol where our preeminent minds gather to carry out the duties of governance, to the Akadaemia Anyder where devotees of knowledge strive to solve the greatest unsolved mysteries of our era, to the smaller but no less valuable institutions─Amaurot has all that you will ever need and so very much more."

HERMES: "No, what troubles me--what I struggle to come to terms with--is the very fact that Fandaniel is stepping down. Does this not mean he will return to the star?"
EMET-SELCH: "Of his own volition, yes. Like so many others have before him."
METEION: "Return to the star? Does that mean...die?"
HYTHELODAEUS: "Well now, that's not a word I hear often...Is that what you say here in Elpis? Mankind is the life of Etheirys. Each of us a drop of blood flowing through its veins, bearing sustenance. In our finite time upon it, 'tis our duty to make it a better place, that all who can call it home now and in future may abide in happiness. To that end, we have dedicated ourselves to the pursuit of enlightened creation. And by our efforts did we transform this once-untamed wilderness into the peaceful paradise which you enjoy today. To return to the star whence we came is a privilege afforded to we who have so loved and nurtured it. A choice embraced by those who have lived their lives to the fullest, in service to our world. And when they depart on this journey, it is beautiful, always."
EMET-SELCH: "The fourteen are no exception. 'Tis believed no occasion is more felicitous than the fulfillment of one's duty. Our office becomes our lives, and to retire is to return, or so the majority of us hold. Some few have elected to eschew custom."
- Editor Note: A prime example of 'involuntary' death being the execution of Athena, but Amaurotine's care for self-preservation is another point of evidence, and the slew of Amaurotines killed by monsters during the Final Days should also be somewhat self-evident of this fact
- Character Interaction text from Euanthe, Elpis (x23.3, y23.6), "Between you and me, Hermes's eating habits are atrocious. We may not be reliant upon food to the extent that our smaller creations are, but our diets eventually catch up with us. If we don't consume the requisite balance of nutrients, we grow weak and lethargic. Yet Hermes consumes candied apples as if they were a staple..." What Euanthe means by "catch up with" is not elaborated on.

ATHENA: "Give me your hand, Lahabrea, and we shall know one another more deeply than ever before."
THEMIS: "Impossible... You bonded your souls?"
LAHABREA: "Aye. That the boundaries between us would cease to be... She offered me everything, to be understood." [...]
ATHENA: "I am become thee, memory and mind..."
LAHABREA: "...And I, thee."
ATHENA'S VOICE:"...Can you feel it? Athena's Voice: My heart... All that I am."
LAHABREA: "Yes. As if it were my own..."
