Background / History

Lucia-Sancus transmigrated into the pre-Shattering Lands Between, arriving in Golden Calendar Year 46 rather than the Tarnished era he knew from his previous life. In his new body, he is the only son of Dragonlord Placidusax and Dragon God Hlaris, hatched from a “Supreme Egg” said to have remained dormant for over a thousand years. As the sole ancient-dragon demigod of the age, he becomes Farum Azula’s legal first heir. 1

The Golden Dynasty summons Lucia to Leyndell as a hostage prince. During the journey, his delegation is targeted by Godskin Apostles, who use the attack on the camp as cover for an assassination attempt against him. The encounter exposes the gap between Lucia’s early strength and veteran “hero”-level fighters such as the Godskin Noble Samuel. 1 2 5

Upon reaching Leyndell, Lucia becomes deeply involved in the politics of the Golden Dynasty, Caria, and the Ancient Dragon Dynasty. He duels Radahn at Lake Leyndell, with both demigods suffering severe injuries, and later helps seal Malenia’s Scarlet Rot. 69 73 78

Over the following years, Lucia uses the Memory Battlefield to train against recorded projections of powerful figures, acquire combat knowledge, and build the Forbidden Research Society. He intends for the battlefield to develop exceptional talents for the Ancient Dragon Dynasty rather than serve solely as his personal means of advancement. 171 249

His later campaigns expand from political maneuvering into conflicts involving Astel, the Northern Realm, Kalerius, and Katepera, the Queen of Death. After Katepera leaves her followers under his command and enters her own spatial-temporal domain, Lucia unlocks the Divine Dominion Throne to pursue and save her. 358 528 554

Appearance

In human form, Lucia appears to be a boy of roughly fourteen or fifteen. He has long silver hair, ice-blue eyes with a faint golden glow, and a slender, swordlike build. 1 39

• His silver hair is frequently mistaken for white hair. 55
• He can assume an ancient dragon form for flight and combat. 541
• He has worn bone armor while concealing his identity. 96
• His dragon characteristics manifest through scales, dragon claws, and black-red dragon lightning in battle. 39 73

Personality

Lucia is observant, calculating, and unusually composed for his apparent age. He evaluates political situations before acting, notices inconsistencies in others’ stories and identities, and regularly plans his growth around future threats rather than immediate gratification. 1 134 277

He is ambitious about power but does not view loyalty as simple obedience. When recruiting Sellen, he states that he wants a partner to explore the unknown rather than a slave, while still deliberately guiding her ambitions toward his larger plans. 170

Lucia is protective of those he accepts as his own. He worries about his soldiers, gives Sellen time to grieve after Yog’s death, takes responsibility for Malenia’s condition, and refuses to abandon Katepera after she entrusts her forces and future to him. 1 277 315 554
