Rhaenyra II Targaryen

Rhaenyra II Targaryen, called  'the Day Queen'  was the very brief nineth Targaryen monarch to rule Westeros, and by technicality the third female monarch of their line -- Though this distinction is more commonly associated with Daenaerys I Targaryen, due to Rhaenyra II's extremely short 'reign'. Historians occasionally count her day-long reign, and some do not.

The sole daughter of Queen Baela I Targaryen and her brother-husband, Prince Consort Aegon III Targaryen, Rhaenyra II was born in a violent and bloody birth that led to her mother's demise. With Baela's death, newborn Rhaenyra II became the Queen of Westeros, but she died the next day. With her death, her father, Aegon III Targaryen, inherited the throne from his daughter.

The direct descendant of Aegon the Usurper through her maternal grandmother Queen Jaehaera Targaryen, Rhaenyra II is sometimes called  'the Last Green Dragon' , for with her demise, the line of the Usurper and his mother Queen Alicent Hightower officially died out.

Early Life
Rhaenyra II was born traumatically. The only child of Queen Baela the Good, it had taken the Queen many years to fall pregnant with her only child, and was celebrated as a miracle from the Mother Above. That miracle turned to terror when the child came early for the aging Queen Baela, and she took to a bloody birthing bed to deliver her. The Grand Maester of the time, Cadwyl, could not save her, and the Queen succumbed within the evening, leaving young Rhaenyra to be the new Queen of Westeros.

Death
Daughter did not long outlive mother, unfortunately. Rhaenyra II only lived long enough to be held by her father, and to be anointed by the Red Keep's Septon, for what little good it did her. She expired the same day of a swift fever, and was burned with her mother.

Legacy
Rhaenyra II is often never remembered independently, and is instead always recalled in the same thought as the demise of Baela the Good. Posthumously, many theories arose around the paternity of Rhaenyra II, as due to her Andal colouring at birth many historians attributed her father to actually be Jaehaerys II Targaryen, who was both said to be very close to Queen Baela and subsequently more bereft than the child's own father at her passing.

If Jaehaerys was Rhaenyra's biological father, that put her conception sometime around the falling out between Queen and Hand over Jaehaerys placing his daughters in the Maidenvault, in late 174 AC. Baela was never recorded nor reported to be disloyal to her husband Aegon, but Jaehaerys had been known to stray from his own wife's bed quite often, and thus it is plausible that the two might have had physical relations that could have led to Rhaenyra, but due to the animosity between them at the time, it raises doubts that they would have laid together willingly.

On the other hand, Aegon and Baela were never said to be close in their marriage, and Aegon was a common sight in the Street of Silk before and after his wife's death, but Baela did visit his bedchamber before her pregnancy was announced. It is entirely possible that Rhaenyra is his child, and that Rhaenyra II simply inherited the colouring of her paternal grandmother, Queen Myrielle Peake.

Regardless of the truth, for the official Targaryen records, Aegon is attributed as her father.

Appearance
Rhaenyra was described as 'small, dark-of-hair, and thin for a babe'. She appeared more Andal than Valyrian.
