In this series, Gleep is a secondary character, a dragon, the pet of the protagonist. The dragon is so young, all he can say is "Gleep" - hence the name.
I (Earl Brown) chose the nickname "Gleep" more than a decade ago. When I realized I needed a good long-term nickname for my online presence, I noticed there were really two types of nicknames; plagiarism and imagination. There were people online using the names "Darth Vader", "Luke Skywalker", "Lord Vader" - all the "big" names from movies or real life. And there were those who had imagination to come up with their own names like "sonOfChAos" or "Beeblequix" (although that one might be plagiarist, too...) Anyway, I wasn&t one of the second sort, but didn&t want to blatantly advertise my lack of imagination, so I chose tu use a lesser-known character&s name for myself.
