Here's why it's unlikely:
* The game was released in 2005. Neopets has shifted its focus towards online games and mobile apps in recent years, making a sequel less likely.
* The Darkest Faerie storyline has been explored in other ways. Neopets has revisited the Darkest Faerie's story through quests, events, and even comics on the website.
However, it's always possible that Neopets might revisit the Darkest Faerie's story in the future, perhaps through a different format like a mobile game or a graphic novel.
The best way to stay updated on any new developments is to follow Neopets' official social media pages and website news.
