This site is NOT a chronology - it is a viewing guide that will assist you through watching the entire franchise in in-universe story order, all the way from the 21st to the 43rd centuries, while making adjustments as needed to ensure an enjoyable viewing experience. It is not rigid - some episodes are shifted in the order to keep things as clear and fun as possible. The guide is updated regularly to stay current with new episodes.
The Original Series S1 · E4
While exploring the energy barrier at galaxy's edge that crippled an earlier ship, Kirk's long-time friend and crewmate Gary Mitchell begins mutating into a god-like entity disdainful of the "mortals" around him.
Just to clarify - the original Star Trek will appear less advanced in terms of its designs and aesthetic compared to the other Star Trek shows we have watched so far, but this is only due to the limitations of television production at the time. This is not “true” in story terms - the technology and society in TOS should be read as on par with Discovery and Strange New Worlds, which all take place at roughly this point in the timeline, and the Enterprise, despite looking different, should be accepted as the exact same ship Pike commanded in Strange New Worlds.
As for the actual viewing order, to fully appreciate the development of the show, it's recommended to watch TOS in production order instead of by air date. In general, don’t get too hung up on continuity with the rest of the franchise in these early days - they take quite a while to pin some stuff down that the rest of the franchise takes for granted.
