The Wheel of Time has an in-depth lore that can be difficult for some fans to wrap their heads around, even if they thoroughly enjoy the series. Aside from its main cast of characters, The Wheel of Time boasts a complicated world, magic system, and interwoven centuries of politics and history that span far beyond the story being told. Due to the source material for the series being a wildly popular fantasy book series by author Robert Jordan, much like another familiar epic fantasy series, Game of Thrones, there are a lot of elements to the mythology within the The Wheel of Time world that need further explanation on screen. The show's writers choose what to change and what to keep, but ultimately, much of the lore remains the same, even if it can be difficult to portray properly in such few episodes. Some of The Wheel of Time's lore diverges from the books. One of the most intriguing dynamics in The Wheel of Time is between the Aes Sedai and their Warders. One of these relationships is front and center by the use of main characters Lan and Moiraine.
