George R.R. Martin Criticizes Targaryen Sigil Error in HBO Adaptations

The author points out inconsistencies in the depiction of House Targaryen's heraldry across 'Game of Thrones' and 'House of the Dragon'.

Martin highlights the incorrect use of a four-legged dragon in the Targaryen sigil, contrary to his design of two-legged dragons.
The error first appeared in later seasons of 'Game of Thrones' and was carried over to 'House of the Dragon'.
Martin emphasizes the importance of maintaining consistency with established canon in adaptations.
Despite this issue, Martin praises other aspects of 'House of the Dragon', including its writing and character development.
The incorrect sigil has even appeared on book covers, much to Martin's frustration.
