Leroy

Leroy was a Demigod in the 90's. His sword hilt is in the Big House Attic. It says ''This broke and Leroy got killed. 1999''

Misunderstood connection to quote about Typhon
The Leroy of this article is not related to the quote, "I was seriously hoping Chiron would say something good, like No, that's our huge friend Leroy, He's going to help us! But no such luck."

Name
Rick Riordan seems to like the name Leroy, because in his other series, The Kane Chronicles, it is used a few times.
