In the opening credits of House of the Dragon Season 2, we're treated to a series of tapestries that illustrate various events from House Targaryen's history. One tapestry in particular, featured in episode 6's intro, depicts what appears to be a Targaryen figure standing in a valley, gripping a sword with both hands and holding it high.
It's unclear whether the figure is about to execute someone lying on the ground or if they're simply brandishing the sword in a powerful pose. There are also two dragons near the Targaryen and another dragon soaring in the sky.
I'm curious if this tapestry might be referencing a specific event from the A Song of Ice and Fire universe. If so, can anyone identify the event, the person wielding the sword, and the identities of the three dragons? I thought the figure might be Aegon I, but his dragon, Balerion (known for its black coloring), doesn't seem to be present.
