"Star Wars: The High Republic" series, often referred to casually as "Carlyle" due to its connection to the characters and stories set in that era, is set hundreds of years before the Skywalker saga. While it's an exciting and well-crafted series, it might not be the best starting point for someone new to Star Wars.
If you're looking for an introduction to the Star Wars universe, starting with "Star Wars: The Phantom Menace" may be a more fitting choice, as it is the first film in the chronological timeline of the series. Watching the original trilogy (Episodes IV-VI) is also a popular starting point for many fans.
Diving into "The High Republic" first could enhance your understanding of the lore and expanded universe, but it would be more meaningful after you have familiarized yourself with the core elements and characters of the main saga. Ultimately, your choice depends on your interests and how you prefer to experience storytelling within the Star Wars franchise!
