Spragg was a humanoid of unknown origin who took care of the Great Machine on Epsilon III.
In 2260, while Draal was using the machine to enlarge the temporal rift in Sector 14, causing a great deal of strain on the machinery, Spragg urged Zathras that they must tell Draal. Zathras disagreed, stating that distracting Draal at that time would catastrophically disrupt the time field and insisted that Draal had left him with specific instructions.[1]
