Knight of Cornfield
Ser Harys Swyft borrowed large sums of money from House Lannister during the rule of Lord Tytos Lannister, like many others. When Ser Tywin Lannister demanded repayment of the gold, Ser Harys, unable to repay it, surrendered his daughter, Dorna, as a hostage into the custody of Ser Kevan Lannister until the debt was settled.

Harys continues to serve as lord treasurer, although his vaults are empty. In order to placate the Iron Bank of Braavos, he writes to the bankers of Myr in hopes of a loan and is advised by Kevan to also write to the magisters of Pentos. Kevan refuses to follow Harys's suggestion of raising taxes as the realm is too full of rebellion and half its lords cannot tell taxation from tyranny. Kevan suggests to Harys that he travel to Braavos and treat with the Iron Bank in person.
Known Knight of Cornfield
- At the start of the series, House Swyft is a knightly house holding the title of "Knight of Cornfield". As there is a "Lord Swyft" during the Dance of the Dragons, it is possible the Swyfts were once a lordly house who held the title of "Lord of Cornfield". If so, the house lost its lordly status sometimes in between the Dance of the Dragons and the War of the Ninepenny Kings (130 AC - 260 AC).
