Brenda J. G. suggests that Katalin Nightseeker could be a reference to either Kaitlan Collins (former host of CNN this Morning) or Kaitlyn Rochelle Dever (Eve Baxter from Last Man Standing). However, since Ms. Collins was still in college when Dragonspyre was released and Ms. Dever didn’t get her breakout role until 2011 (two years after Dragonspyre), I’m going to count this one as unconfirmed.

Brenda J.G. suggests that Oskar Crowfriend could be a reference to Oscar Crawford. However a Google search lists 6 different Oscar Crawfords each of whom could be the reference. Unconfirmed.
