Round 4: Maniacal
Xenophilius Lovegood was known for his maniacal ideas. He stayed sane and normal enough that people ignored him for the most part because he knew that getting too wacky would result in bad attention to him and his daughter, Luna.
The Quibbler was one of the aforementioned ideas. In Xenophilius' eyes, the Daily Prophet was so boring and normal. It went on and on about subjects that he couldn't believe anybody found interest in.
Thus, with the help of his wife, he started an alternative option to the Prophet. In it, he wrote about much more appealing topics, like Crumple-Horned Snorkacks. Everybody wanted to read about Crumple-Horned Snorkacks.
The Quibbler didn't bring in too much income at first, but it was enough for him and Pandora and Luna to live a happy life. Besides, even if the Quibbler didn't satisfy anybody else, he and his family enjoyed it plenty.
But sometimes, his ideas in the Quibbler were too dangerous.
His maniacal ideas were what got Pandora, his lovely wife, killed.
It had been Xenophilius himself who had proposed the specific experiment, and the two of them had been working on the project together. Luna was young at the time.
He knew it would be mildly dangerous, but they persisted onwards. Once they had started, they couldn't bring themselves to stop.
One false calculation and one large explosion later, Pandora was dead because of him and his maniacal ideas.
His maniacal ideas were what got Luna kidnapped.
He had been writing a lot more in the Quibbler about Harry Potter, and they were positively positive about him, not taking the negative stance against him like the Prophet.
Xenophilius had been safe originally with the level of wackiness that the Quibbler was at, but as he continued on writing more articles about Harry and the Order, he was oblivious to the quickly rising danger levels. Before he knew it, there had been another simple false calculation and Luna hadn't come home to him at Christmas.
His precious daughter hadn't even done anything awful herself. The Snatchers had only taken her because of him and his maniacal ideas.
Sometimes, Xenophilius wished that he could have his maniacal ideas and everything, but only without all the pain and harm they caused to his loved ones and himself.
But that would be the ideal life, and a Lovegood never gets the ideal life.
