House of the Dragon - Syrax Dragon Flight

Syrax is one of the very few known she-dragons in the story. This has been confirmed by the histories of Westeros long ago, and in House of the Dragon's very first episode, Rhaenyra confirms that Syrax is, in fact, a she-dragon.
This is fitting for a character such as Rhaenyra who aims to be Queen of the Seven Kingdoms and claim the Iron Throne for herself. With Syrax by her side, Rhaenyra is able to fight even the toughest of battles with great confidence.
Princess Rhaenyra Targaryen claimed Syrax to be her mount in 104 AC. At the time, Rhaenyra was just 7 years old and upon seeing the dragon, she immediately described it to be very young. Immediately afterwards, Rhaenyra named the beast Syrax, which once again goes to show that she had no other riders before.
