Recent findings (audit lane, verbatim)

Daemon Targaryen — Daemon was not Master of Coin; he was Master of Laws from 103–104 AC.

Daemon Targaryen — Daemon did not support Viserys's claim at the Great Council of 101 AC; he was a candidate himself and lost to Viserys.

Rhaenys Targaryen — Rhaenys is Viserys I and Daemon Targaryen's first cousin, not first cousin once removed

Rhaenys Targaryen — Aemon Targaryen was the third son of King Jaehaerys I, not the second

Jacaerys Velaryon — The entry states Jacaerys was named Prince of Dragonstone in 120 AC when Rhaenyra was named heir, but Rhaenyra was named heir in 105 AC, not 120 AC.

Jacaerys Velaryon — The entry omits that Jace drowned after falling from Vermax, which is a key detail of his death.

House Targaryen — The intro states 'ruling from King's Landing roughly 129 years after Aegon's conquest' — this is ambiguous and inaccurate because House Targaryen ruled from King's Landing from 1 AC onward, not starting 129 years later.

House Targaryen — The intro says 'Set about 169 years before Game of Thrones and 172 years before Daenerys Targaryen's birth' — the Dance of the Dragons ends in 131 AC, Game of Thrones begins in 298 AC (about 167 years before), and Daenerys is born in 284 AC (about 153 years be

Vhagar — Vhagar was not first bonded to Queen Alysanne Targaryen; she was originally ridden by Visenya Targaryen.

Vhagar — Vhagar was not born after the Doom of Valyria around 52 AC; she was born before the Doom and was already alive during Aegon's Conquest.

Dance of the Dragons — The Fishfeed is not a battle from the Dance of the Dragons; it is from the First Blackfyre Rebellion.

Maegor the Cruel — Balerion died during the reign of King Jaehaerys I, not Viserys I.

Maegor the Cruel — Aegon the Uncrowned was Maegor's half-nephew, not his nephew, and he was killed by Balerion, not in single combat with Maegor personally.

Dark Sister — Dark Sister is described as a 'hand-and-a-half sword (bastard sword)', but in canon it is consistently depicted as a longsword, not a bastard sword.

Dark Sister — The entry states 'Primary Wielders=Daemon Targaryen' without mentioning other canonical wielders such as Visenya Targaryen or Brynden Rivers.
