Fans will notice that the opening credits have had a drastic makeover, moving from a model of Old Valyria tracing bloodlines and rulers of the Targaryen dynasty to a tapestry illustrating the rise of House Targaryen and the beginning of its demise.
The original opening credits of the series changed as rulers married, had children, and died, meaning we can expect this tapestry to morph and grow longer as the latest season progresses.
Showrunner Ryan Condal said that the original credits, which served the first season perfectly, had “run out of runway” for the second.
To sum it up as concisely as possible, the tapestry highlights key points in Targaryen history, bringing us up to date with the final events of House of the Dragon’s first season.
