CASSIE WELLS Cassie was a whiz kid in her childhood, graduating high school at the age of 16, and already had her Master's Degree in Physics at age 21. Currently employed as a nanotech engineer at TerCon Technologies, a research & development facility in the Dallas area, Cassie was experimenting with fabricating elements when she discovered that one of the elements she created could travel through time. She then harnessed this strange power of this element to make her own time machine. Cassie is an outgoing, adventurous type, a bit uninhibited, and always willing to help out someone in need.
	MATT GAHAN One of Cassie's closest friends, Matt Gahan is a travel agent who likes seeing the world. Being an expert in electronics, Matt got involved with Cassie's time traveling right from the start, when Cassie asked him to help her assemble the time machine using a brass pendant and a small flip phone. He's also a bit of a prankster who would play a practical joke on the President if he thought he could get away with it.
	BETHANY GIBSON Bethany is Cassie's best friend - going back to high school times - as well as her roommate. She works at TerCon as the receptionist. She's a bit more introverted and self-conscious than Cassie and Matt, but she's still a friendly and personable woman.
	KEITH SCOTT Keith Scott is a Special Agent for the FBI, specializing in espionage and paranormal investigations, and one of his regular assignments is keeping tabs on Cassie and her friends making sure their time traveling doesn't get out of hand. As a dwarf, Keith's diminutive size enables him to conceal himself in places other agents wouldn't be able to fit in.
	MAGGIE HARPER OSTERMAYER Maggie was originally born in Ireland in the early 14th century, and would have been dead from the Black Plague if Cassie hadn't befriended her while visiting medieval Dublin. After some lifesaving medicine to cure the plague, Maggie decided to permanently accompany Cassie to modern times. She now works in the Public Relations department of TerCon and spends a lot of her free time volunteering for various non-profit organizations. Maggie met Rodney at TerCon in 2006, and they married in 2008.
	RODNEY OSTERMAYER Rodney works at TerCon as a Sales Agent. He and Cassie get along well... unless college sports are involved. Then it's a clash of alma maters, his being the Texas Longhorns and hers being the Oklahoma Sooners. Rodney is currently married to co-worker Maggie.
	NICKI DARLING Also known as MIRA-7 Serial Number X202-S197-OAJ, Nicki is a Multifunctional Interactive Robotic Assistant, first manufactured in 2023 and purchased by Cassie in 2027. Cassie then had her reconfigured to resemble what Vicki from the "Small Wonder" TV show would possibly look like as a woman in her twenties. Nicki has 500 exabytes (half a trillion gigabytes) of memory, a fully customizable body, built-in wireless internet capabilities, and her own time machine that she can use to obtain information about the future for Cassie.
