Wizards of the Coast recently filed an application to register Dark Sun in the US, a sign that D&D could be bringing back the campaign setting in the near future. The trademark claim was filed on October 13th, 2025 and is poised to replace a previous trademark that was cancelled by the USPTO in 2024. The trademark, like most involving D&D properties, covers both “downloadable electronic games,” “games and playthings,” and “entertainment services.” Similar active trademarks exist for other D&D campaign settings such as Spelljammer and Forgotten Realms, although neither of those have lapsed in recent years.
We’ll note that, as the previous Dark Sun trademark lapsed a year ago, this could be a case of simple paperwork, or it could be the latest sign that a Dark Sun product is eminent. Earlier this year, Wizards released an Unearthed Arcana for the Psion class and several subclasses that all but spelled out a return to the setting, complete with mentions of sorcerer-kings, gladiatorial fights, and preservers and defilers.
