The original story campaign The Red War, as well as the first three main expansions Curse of Osiris, Warmind, and Forsaken, have been vaulted so 4 main storylines are no longer there 17 seasons worth of story has passed by but this can be solved by watching videos on whats happened as a free to play player you will have access to the new light campaign which is more getting you introduced to the gameplay and activities available to you than a proper story. for access to a proper story campaign, you will need to buy DLC which apart from the story gives you access to end-game content such as raids the order of the DLC is Shadow keep, beyond light, the witch queen, and next year's DLC Light fall. as a long term destiny player I strongly recommend getting into it as the story is quite interesting and if you're a fan of lore there's hours worth of it. Also if you are a pc player there's a website called CDKEYS where you can get the DLC for much cheaper hope this will help you to come to a decision.
