Battle Above the Gods Eye

The Dance over Harrenhal was an aerial duel during the Dance of the Dragons between two of the most powerful dragons, Vhagar and Caraxes, and their riders Prince Aemond Targaryen (fighting for his brother Aegon II Targaryen) and Prince Daemon Targaryen (fighting for his niece-wife Rhaenyra Targaryen.

History
Daemon Targaryen riding the dragon Caraxes met in a one on one fight against Aemond Targaryen riding the great dragon Vhagar in the skies over Harrenhal. The aerial duel reached its climax when Daemon made a stunning mid-air jump from Caraxes to Vhagar's back, hundreds of feet above the ground, and killed Aemond.

Their clash resulted in the death of both men and both dragons.
