What is the last world in wizard101?

As of my last update, the latest world in Wizard101 is "Lemuria," which was released in 2021. This aquatic-themed world introduces players to new quests, creatures, and challenges, expanding the game's storyline and lore. Players can explore various regions within Lemuria, including underwater cities and unique landscapes. Keep in mind that new content may have been added since then, so it's best to check the official Wizard101 website for the most current information.
