I don't know what the fuck a Pillar of Creation is!

[ aaaaand then a bit of the insight hits. Right. He doesn't know what a Pillar of Creation is. And he didn't even bother to ask about what a Pillar of Creation is, this isn't something that could arguably be RM's fault as well (because Strange will go to his grave saying that the petty gem argument was at least partly Lapis and Peridot's fault). ]

So I suppose this is me asking. What exactly is a Pillar of Creation and why would it be a bad idea to give all of it's magic to one person?

[ And look, he's tired of almost drowning, so don't mind Strange as he awkwardly starts doggy paddling towards the edge of the lake. ]
