The main characters in the Spectra series novels are not clearly defined without more specific information about the series. But in general, we can assume that there are likely to be characters with special abilities. Maybe there's a character with the power to manipulate time in the Spectra - related events. There could also be an older, wiser character, like an old wizard or a sage, who guides the younger characters through the mysteries and perils of the Spectra realm. These different characters with their distinct personalities and abilities interact to create the rich tapestry of the Spectra series novels.

Together, they face the challenges presented in the Spectra world. The relationships between these characters, like their rivalries and friendships, are what drive the plot forward in these novels.
