The eldest daughter of King Aegon III was sixteen when her brother Baelor ascended the Iron Throne, dissolved his marriage to her (which had been celebrated but never consummated), and confined her and her sisters to their own apartments in the Red Keep, soon known as the Maidenvault.

Daena was Targaryen to the bone; strong, beautiful, wilful. Her silver-gold hair was thick and curly, a wild untamed mane that tumbled down across her shoulders and framed a heart-shaped face, a pair of sparling purple eyes, and a fearless "I'll dare anything" smile. She was a wild almost from birth, lithe and athletic, a runner, a climber, and an expert horsewoman. "I was born to ride a dragon," she liked to say, but the dragons were dead. Daena was expert at riding at the rings, though she was never allowed to joust in an actual tourney. She was also a hunter, and a fine archer with her short recurved bow. She worshipped her father and idolized her brother Daeron, the Young Dragon.

Daena's dress was often as dramatic as she was. As a child she often dressed all in black, like her father King Aegon III. After her brother Baelor failed to consummate their marriage, she changed to all white, and vowed to wear nothing else until she had been properly bedded, in hopes of shaming him. (It did not work. Baelor liked her in white, feeling that it made her look more innocent). Later, as a pampered prisoner in her brother's court, Daena made several escapes, usually by dressing as a washerwoman or serving girl (once with the connivance of her cousin, Aegon).

You could legimately depict her in the simple brown skirt and laced bodice of a peasant girl -- in her hunting leathers, with her bow and quiver -- in her white post-wedding court clothes -- even in the blacks she wore as a child. No matter how she was dressed, however, she always wore the golden three-headed dragon pendant she had inherited from her father. At court she wore it on a fine golden chain; when in disguise, she hung it on a leather thong and hid it beneath her clothes. Supposedly she even wore it when bathing, and when making love.

She became known as "Daena the Defiant" when she turned up pregnant, and refused to name the father. Her son was born robust and healthy, with the purple eyes and silver-gold hair of the Targaryens. Daena named him Daemon. Years later, when he distinguished himself as a squire, his father (who by that time was the king) presented him the sword of Aegon the Conquerer, and from time forth he was known as Daemon Blackfyre.
