Vermithor Emerges at Tumbleton, Not Vhagar
In the House of the Dragon Season 3 finale’s Battle of Tumbleton, Caraxes leads the assault on Silverwing while a larger dragon appears in the sky—revealed to be Vermithor, not Vhagar. Vermithor and Silverwing are bonded, suggesting Vermithor defends Silverwing rather than aiding Caraxes. Tessarion makes a brief cameo; Hugh Hammer pursues his wife Kat, who dies, fueling grief that could drive future dragon-rider shifts. The episode leaves questions about casualties and hints at possible rider switches in Season 4.
