I occasionally have characters from television/movies/books etc make appearances. Some of my favorites have been:
- A wandering soldier named "Casey Romaine" (one of the modern-day aliases of Casca, the Eternal Mercenary) as a mercenary who crops up from time to time.
- Brigadier General Jay Corbett (the "Witchmen" military commander from the Horseclans series) as the military adviser for a mixed group of University of Florida researchers and displaced Seminole Indians fighting a guerrilla war against the New America enclave in Saint Petersburg.
- Colonel Phillip Green (Star Trek) as a New America commander.
