An Ancient employed as a teaching assistant at Akademia Anyder. Ostensibly, he researches complex intelligence in artificial creations, but based on the number of times he's been sent to work in Phytobiology as a punishment for impertinence, one would be forgiven for assuming he's a plantkeeper. He's restless by nature and travels far afield on his sabbaticals, often running into Azem on his trips abroad. His greatest joy in life is getting a rise out of his bosses, and he has a soft spot for familiars; the more intelligent they seem, the more interested he becomes.
The creator of the Dawn's Cradle free company who brought Hydaelyn's chosen Warriors of Light of this age together. They see a cataclysm looming on the horizon, and have taken it upon themself to gather heroes capable of combating this threat - and are willing to walk together with them unto the end. Their rune fencing art is a relic of a bygone era which combines twin blade sword arts with augmentative magic.

Light is the shard of, and has the memories of, an Ancient once named Euphrosyne and titled Azem. Euphrosyne was able to pass their memories on to a baby Miqo'te, either as a failsafe, or as a last hope. Though Euphrosyne and Light are different people, their fates are deeply intertwined, and personalities very alike, so much so that those who know Euphrosyne note a striking resemblance in Light. Light also possesses Euphrosyne's crystal, given to them by the shade of Hythlodaeus in Amaurot.
A Garlean deserter given new lease on life by the Lemures, who taught him to fill the emptiness inside him with friendship, joy, and kinship. He joined Dawn's Cradle after competing with them on a contract and losing badly. These days, he's enjoying the life of a lauded hero and 'heart-throb', though his voidsent partner tends to scare off most of his potential dates.
A mysterious young woman who keeps her past tightly under wraps - admitting she's an Oracle of Darkness meant to serve as host to Zodiark's Will isn't easy. Light offered her a place of sanctuary in Dawn's Cradle, where she could safely pursue her research; in turn, Morgan supports the free company's activities with her inherited fortune. She wields a recreation of a Zodiac Brave's arm, the Lilith Rod Zeta, which absorbs a fragment of a fallen enemy's power to strengthen itself.
Qualia is a Paladin from the Valnain region of Dalmasca, who lived and worked among the various adventuring clans during the reign of King Raminas keeping the outskirts and trade routes safe. As Garlean patrols and outposts became more common, trade dried up, and Garlean soldiers poached their Hunt marks in their expansion. Though it broke their heart to leave their home behind, Qualia had no choice but to leave Valnain and seek out opportunities abroad. They met Light while working with the Eorzean Adventurers' Guild prior to the Calamity and fought together with them at Rivenroad to destroy the Meteor beacon, and the pair have worked closely together for all the years since.
Tarak is an armorsmith by trade, born in Garlean-occupied Bozja where his family had lived for generations, though factory work took him to the capital. The Bozjan Incident took his mother, and the Calamity and wars abroad took the rest of his family; his depression sank his marriage; and his job was made redundant by innovations in technology; thus, with nothing to his name and no one to miss him, Tarak traveled south, hoping to start a new life somewhere the Garleans couldn't touch.
He met Dawn's Cradle while he was still learning armorcraft - they were his first commissions, in fact - and they were impressed enough with his work that, as they grew as adventurers, they relied on him for armor and weapons alike, forcing him to branch out in disciplines to augment his armorcraft. Qualia hired him on as the company's smithy as soon as he'd obtained his journeyman's license, and though most of their arms are Gerolt-make these days (the exceptions being Jakka, who still uses the axe she brought from home, and Light, whose twin blades are still as sharp as ever), the free company still relies on him for armor.
A dancer from Nagxia, where she had been a dancer in her aunt's opera company since her childhood; her grace and beauty were well-renowned in her hometown, and she even had a suitor chosen by her family. War in the Calamity's aftermath drove her family to flee to neutral Kugane using their connections, where they would find work at a theater in the arts district. Xueyi was scouted by Troupe Falsaim during one of her performances, and her contract bought out that very day; just days after her final performance she was on a ship bound for distant Radz-at-Han and, eventually, Limsa Lominsa. She now travels with Troupe Falsaim across Hydaelyn's breadth, bringing smiles, laughter, and hope to those burdened by war and strife.
As a dancer, Xueyi is able to use chakrams, spears, sabers, and poles in combat. She favors her spear, whose weight and balance makes it easy for her to wield despite her small stature. Despite her lingering grief over the future she lost, she's hopeful for what her future may have in store.
