According to Deadline, HBO has enlisted Helstrom executive producer Amanda Segel to write one of their upcoming Game of Thrones spinoffs that is currently in development.
Segel has signed on to pen the story of 10,000 Ships, a prequel series centered around Princess Nymeria and her journey from Essos to Dorne.
This news comes a month after production on HBO’s first Game of Thrones prequel series House of the Dragon had officially begun.
This migration took place around 1,000 years before the events depicted in the A Song of Ice and Fire novels.
