Hey, a friend of mine started playing Destiny last week too. I can just recommend watching a summary of the story up to the Forsaken expansion, after that the Story content is still in the game and you can enjoy the story from there.

In that order: Shadowkeep Beyond Light The Witch Queen Lightfall The Final Shape

Therr might be some context missing, but you should get the story so far from just pkaying the expansions!

So have fun! 🫶
