Ser Mervyn Flowers

Ser Mervyn Flowers was a Kingsguard knight named among the conspirators against Aegon III. His brief but violent end, at the hands of the men who came to arrest him, places him within a plot whose participants and leadership remain clouded by accusation and uncertainty.

Identity and Alleged Involvement

Flowers is identified as a member of the Kingsguard and one of the men named by Lord Graceford, the Lord Confessor, when he disclosed the names of other conspirators. The account says the sight of the instruments of torture was enough to make Graceford speak; it does not establish whether Flowers was guilty or explain his precise role in the conspiracy.

The accusations emerged amid competing claims about the plot. Some of those later confined in the black cells said they had acted from an honest belief that Thaddeus Rowan and the Lyseni were traitors. The account does not record Flowers making that defense, so his own motive and understanding of the conspiracy remain unknown.

Confrontation and Death

Ser Marston Waters, himself a Kingsguard commander, chose to confront Flowers personally. The two were both bastards and sworn brothers. When Waters told him of Graceford’s accusation, Flowers drew his longsword and offered its hilt, but seized Waters’s wrist as he reached for it and stabbed him with a dagger.

Flowers made it only as far as the stables. There, while trying to saddle his horse, he killed a drunken man-at-arms and two young stableboys. The noise brought others running; they overwhelmed and beat him to death. He died still wearing the white cloak of the Kingsguard, an ending that joined his failed escape to the public disgrace of the order he had sworn to serve. Waters, gravely wounded in the encounter, was carried to Grand Maester Munkun and died that same night.

Place in the Conspiracy’s Uncertainty

Flowers’s death did not settle who had directed the plot. Mushroom’s account suggests that the named conspirators may have been instruments of a more powerful figure, and observes that the Kingsguard were accustomed to obeying commands rather than issuing them. It points toward Unwin Peake as the man connected to the others, but presents this as a shadow hanging over the Red Keep, not a proven conclusion about Flowers’s part in events.

Within that uncertainty, Flowers is defined most clearly by the contrast between his office and his actions: a sworn protector who attacked a fellow Kingsguard, killed three others while fleeing, and was himself killed before he could escape. The evidence records the accusation and the violence, but leaves his place in the larger design unresolved.
