Unlike Martin's "A Song of Ice and Fire" novels, which are told from various people's point-of-view, "Fire and Blood" reads more like a SparkNotes version of a House Targaryen history textbook.
For many events, multiple accounts of what happened are offered by the fictional historians. This means the TV writers hired for HBO's adaptation had a lot more leeway with the story. Any accounts may have been uninformed or biased, but now "House of the Dragon" is able to create a consistent canon of events.
So let's take a closer look at some of the major deaths in "House of the Dragon" so far, and how they compare to the details found in "Fire and Blood."
