8. Gored by a Boar
Who: Robert Baratheon
Gory details: Besides giving her servants the side-eye and fooling around with her brother, Cersei's other favorite hobby is plotting. She has Robert's squire serve him extremely potent wine during a hunt in the Kingswood. When Robert finally tracks down a boar, he's so drunk he misses the shot; the boar charges, and Robert dies in bed several days later. The Ruler of the Seven Kingdoms is dead — but not before naming Ned the Protector of the Realm until Joffrey comes of age.
Narrative importance: Robert's demise is the catalyst of the War of Five Kings. In the meantime, while helping Robert write his will, Ned replaces “my heir" for “my son Joffrey," since he knows Joffrey's father is actually his uncle.
Degree of difficulty: Intermediate. With a little luck on her side, Cersei was working a few thoughtful moves in advance, banking on Robert to get sloshed enough to either kill himself or not notice if someone turned on him to finish the job.
