Baldur's Gate 3 companion Astarion is a man of many secrets. When he joins the party, he hides his past, his scars, and even his identity as a vampire spawn—although that one doesn't stay secret for long. Players who want to learn more about Baldur's Gate 3's snarky rogue need to invest time and effort in his story, but some of his secrets are so well-hidden that they can only be learned from paying the closest attention to everything about him, such as examining his gravestone during one late-game cutscene.
