I Thought Volo Was A Bard

So I did my play through, thought Volo was an interesting side character and moved on without another thought on him. Then I found out that he has been around for a long, long ass time when I realized he had written a bunch of in-universe books.

Now people live a long time in this world, but he is a human, which have normal life spans. So I look it up and he’s a freaking Weave Anchor and a Wizard??

I thought he was a bard. I’m flabbergasted. That is all
