Star Wars Character Encyclopedia: Updated and Expanded was given a sneak peek by the official Star Wars website. It releases in April and is filled with information on every character.
The encyclopedia reveals some new facts about classic characters like Han Solo and new characters like Korr Sella and Grummgar who weren't featured prominently in The Force Awakens. You can check out more images of the encyclopedia here.
It looks like that even with the updates, the entries shown remain largely spoiler-free and don't include many plot details from The Force Awakens.
For those looking to dive even deeper into the Star Wars lore, publisher DK also released a visual dictionary for The Force Awakens back in December. The latest Star Wars movie's list of voice actors was also recently revealed.
