Corona Pollentia brain

“Corona Pollentia,” I said. “She has powers.”

“They take different forms. There aren’t hard and fast rules. But I’ve heard that if you trigger young, it takes more of a hold, with more… it’s called dimpling. Like a hand is actually pressing it down into the brain. That right there looks like dimpling.”

“You get more cloudiness in some kinds of scans where it expands out into the webbing around the brain, but we’re not getting that. It’s been way too long since I studied this,” I said. “The corona starts as a single marker, like a quarter-sized knot in wood, or a ball the size of a golf ball, pushed between the two lobes. Then when we trigger, it surges into life. It’s part of the reason we black out. It expands slightly, veins swell. But most of the time an unactivated corona is hard to tell apart from an activated one, and a surprising number of people have unactivated ones. Sometimes you look at them and the larger veins or structures suggest what the power is linked to.”
