[More Star Wars spoilers ahead]
By this point in the Star Wars timeline, Obi-Wan has had quite a ride. Let’s recap the hero’s journey so that you can go into the new series without any gaps in memory…
So, firstly, Obi-Wan Kenobi was born on planet Stewjon, and he was quickly trained and made a Padawan under Jedi Master, Qui-Gon Jinn. Later, he witnessed the death of his Master and then managed to kill the perpetrator, Darth Maul.
Sticking to the promise he made to Qui-Gon Jinn, Obi-Wan trained Anakin Skywalker. Over time, the evil Chancellor Palpatine managed to corrupt Anakin and convert him to the dark side. All the while this was happening, Obi-Wan defeated the feared Jedi-hunter, General Grievous.
After finding out about Anakin’s corruption, Obi-Wan engages in a brutal duel, and Anakin is left to burn in the planet’s lava. Obi-Wan then makes it his quest to conceal Anakin and Padmé's twins, Luke and Leia, from the Sith (with the help of Yoda). The last thing we see is Obi-Wan going into exile on the planet of Tatooine, to watch over Luke Skywalker.
Given that Obi-Wan Kenobi is set to pick up a mere 10 years after these dramatic events, I’m going to take a wild guess that Darth Vader is going to be hell-bent on getting his revenge. Eek!
