Rosby
Rosby is a modest but strategically significant holdfast in the crownlands, sworn to the Iron Throne. Its lord, Gyles Rosby, served as master of coin and lord treasurer on Cersei Lannister's small council until his death from a persistent cough. The Rosby inheritance, with six claims put forth, becomes a minor but telling point of friction on the small council during the regency of Ser Kevan Lannister, as Grand Maester Pycelle attempts to bring the matter up for discussion only to be deferred by the Lord Regent, who has more pressing concerns with the trials of the two queens and the threat of the Golden Company's landing in the south.
Succession Dispute and Political Context
The Rosby succession is first raised by Grand Maester Pycelle during a small council meeting in the throne room, where he lists six claims that have been submitted. Ser Kevan Lannister, acting as Lord Regent, immediately dismisses the matter, saying, "We can settle Rosby at some later date. What else?" This deferral occurs in the context of a council already strained by the competing interests of Lannister and Tyrell factions, with Mace Tyrell as Hand of the King and Randyll Tarly commanding the army on the Trident. The Rosby lands and incomes would be a valuable prize for whichever house could secure them, and the delay suggests that Ser Kevan is unwilling to open a new source of conflict while the realm faces more existential threats from Stannis Baratheon in the north, ironborn raiders in the west, and the sellsword army of the Golden Company in the south.
Narrative Significance
Rosby's role in the narrative is primarily as a barometer of the political maneuvering in King's Landing during the interregnum between Cersei's fall and the assassination of Ser Kevan. The fact that Pycelle, a Lannister loyalist, presses the issue while the more powerful lords are content to let it lie indicates that the Rosby inheritance is a secondary concern, a piece of patronage to be distributed once the more immediate crises are resolved. The deferral also reflects Ser Kevan's cautious, managerial style of rule, as he seeks to avoid unnecessary quarrels with the Tyrells and their allies. Ultimately, the Rosby succession is never settled within the text, left hanging as one of many unresolved threads when Varys murders both Ser Kevan and Grand Maester Pycelle, plunging the regency into chaos.
