Rick and Morty Kingdom Balls #1

Among Rick’s things, Morty discovers a scrotum-handled shining sword dating back to Rick’s days as a member of the Ball Bladers, a brotherhood that would “wield this weapon with honor and grace to bring order and glory to the four Story Realms.” The Story Realms being “deadly physical manifestations of the great story frameworks”, which are all about different types of conflict. Morty’s mishandling of the sword results in a portal opening and swallowing-up Rick, Morty, and Jerry (who just happened to blunder into the moment) and depositing them in the first Story Realm's conflict “Man v Man”.
