Finding out about Spock's early life.
Although TAS is not considered a canonical part of Star Trek, elements of Spock's backstory established here have made it into official sources and future live-action episodes of TNG.
My year for this episode is estimated from the Stardate; it is one of a group of TAS episodes set between 'The Empath' and 'The Mark of Gideon'.
This episode is a nominee for the DITL "Best of Trek" award.
Spock emerges from the Guardian of Forever to discover that history recorded his death at the age of 7 whilst undergoing the Kahs-wan ordeal. He travels back to the year 2237 to save his own life and restore the correct timeline.
