Think about it. Rick Riordan didn't start mentioning dark clouds consistently in the series until about the time I joined this site. Also around that time, he found a lost puppy and decided to adopt it. Now bring in the fact that some users think I am really Rick Riordan in disguise and only come onto this site to get ideas for the series, and it makes perfect sense.
