The Cat’s Leg Dagger is shown in the first episode of House of the Dragon, as the vision known as “Song of Ice and Fire” is explained to Rhaenyra. We knew the weapon had significance to the Targaryen family, and it was well known that it was once wielded by Aegon the Conqueror, passed down through the family ever since. At the end of “King of the Narrow Sea”, Viserys tells Rhaenyra some additional history about the dagger.
He reveals that the dagger belonged to Aenar Targaryen, before it was passed to Aegon. Aenar was a dragon lord of ancient Valyria and a central figure in House Targaryen. Aenar’s daughter, Daenys, is known as “the Dreamer”, and she had a vision to leave ancient Valyria before it was destroyed. Aenar listened to his daughter and left town, eventually settling in Dragonstone.
Aegon also has a dream, the one known as the Song of Ice and Fire, the prophecy of winter taking over Westeros. Viserys reveals to Rhaenyra that the cat’s paw dagger is a physical representation of this devastating sight. As he thrusts the dagger into a flame, Aegon’s words are lit up: “From my blood comes the prince that was promised, and his will shall be the song of ice and fire.”
The dagger was always meant to strike down the Night King upon his arrival in Westeros, but his death was meant to fall at the hands of the promised prince. Arya is the one who ultimately uses the gun to kill the series villain, but that part of the story wasn’t written in George RR Martin’s book series.
