Didn't pay much attention to Destiny's story? Didn't read the Grimoire? Or just didn't follow it's vagueness? Well Game Informer has you covered! Today's article in their month long coverage summarizes the story of the base game and both expansions, as well as the lore you can only find in the Grimoire (and there may even be a few hints about story to come). Give it a read if you're not confident in your knowledge! (Thanks Dooskey for pointing it out on the forum).
