House Peake
Proud marcher lords who once held three castles — Starpike, Dunstonbury, and Whitegrove — and lost two for backing the black dragon at Redgrass Field. Lord Gormon Peake counts that debt daily, and means to collect it at Whitewalls with another man's crown.
The fuller tale
Three Castles, One Due reads, on a Peake banner today, less like a motto than a grievance filed in heraldry — the house once held Starpike, Dunstonbury, and Whitegrove, and lost two of the three when it backed the black dragon at Redgrass Field, leaving Lord Gormon Peake with Starpike, three black castles on orange that now describe an inheritance rather than a boast.
Where Ser Eustace Osgrey's losses left him wistful, Gormon Peake's left him calculating. He is not a man given to reciting old glories for their own sake; he is a man who has spent fifteen years doing the arithmetic on exactly what is owed him and by whom, patient in the specific, cold way of a debt collector who has never once forgotten a figure.
That patience finds its outlet at Whitewalls, where Gormon Peake is the plot's actual spine — the lord who does the recruiting, holds the wavering conspirators together, and brings a disguised Blackfyre pretender into Lord Butterwell's wedding under cover of celebration, all while lesser men like Cockshaw and Heddle handle the plot's louder, riskier edges.
What he wants out of it is never disguised as anything grander than it is: a restored Blackfyre monarchy that would, presumably, restore Dunstonbury and Whitegrove along with it. It is a personal ledger dressed up as a political cause, and Gormon Peake would likely tell you, if pressed, that he sees no reason to distinguish between the two.
The ledger goes unpaid. Bloodraven's net closes on Whitewalls before the conspiracy can strike, and whatever else the failure costs the other plotters, it leaves Lord Peake exactly where he started — one castle, one due, and fifteen more years, at least, of counting.

Lord Gormon Peake and the Whitewalls conspiracy belong entirely to The Mystery Knight, which no season has been built from; his role as the plot's organizer is, for now, known only to readers of the novella.
