As the seventh season of Game of Thrones approaches, it looks like the main conflict will be between the three rulers with claim to the Iron Throne: Queen Cersei Lannister, King in the North and rightful heir Jon Snow, and prospective queen Daenerys Targaryen. But because Sherlock’s Mark Gatiss has confirmed his return in two Season 7 episodes as the enigmatic Tycho Nestoris, Cersei’s downfall might come from an unexpected source.
Tycho Nestoris first appeared in Season 4 as a representative of the mysterious and monolithic might of the Iron Bank. The Iron Bank of Braavos controls the finances of the Known World, and whereas the Lannisters always pay their debts, the Iron Bank always collects its debts. Unfortunately for the Iron Throne, it is heavily in its debt.
Tycho Nestoris was unimpressed with Stannis Baratheon’s rhetoric when he first appeared in Season 4, and in Season 5, he was even less impressed with the bumbling Mace Tyrell. Nestoris could bring Cersei down before Daenerys even gets a chance to, because he’s reportedly leaving his home base of Braavos to come to King’s Landing.
That’s how serious he is about collecting the debts Cersei now owes. For a Queen who rose to power through gloriously blowing up half of King’s Landing, it would be a harsh ending for Cersei to be taken down by bureaucracy.
Game of Thrones Season 7 premieres on July 16, 2017.
