Curse of Knowledge

The Curse of Knowledge is an incredibly rare power rarely given to select demigods at birth. If you have the Curse, you can literally know everything you want to, even if people don't want you to. Even if heavy magic is covering something up, you could know what it was. Demigods who have it were incredibly powerful and valuable. Most die before they reach ten. If you have it, Nemesis will curse you with special weaknesses to prevent you from being too powerful.

Known Demigods with the Curse

 * Riley Jackson, a daughter of Percy Jackson and Annabeth Chase, possesses the gift. She has eosinophilic enteropathy and asthma to make up for her power. Riley is also incredibly powerful at sword fighting. She found out about the gift when she was ten when her sister Kristin asked about them. The Keys were accidentally created thousands of years ago and were hidden. Anyone who knew where they were or even that they existed were in serious trouble. Percy, Annabeth, Piper and Jason were kidnapped because they knew where they were. When Thalia and Luke were asked, they looked at each other as if they didn't want to say, but Riley explained them. When they asked her how she knew, she said "All of a sudden I knew what they were." Kristin asked Thalia and Luke if they knew where they were, and they shook their hands. Then Riley shook and when asked what was wrong, she replied "I know where they are."
 * A unknown son of Hermes in the 16th century. After him, no one possessed the curse until it was discovered in Riley. He was killed by monsters before he was 8. The Titan Enceladus said about him that they killed him too early, he wanted to get the Key's location out of the boy.
