Reger was a male inhabitant of Beta III in the 23rd century and the father of Tula. He was part of a resistance that was organized in threes; Tamar was his contact, and he did not know who the other member of the cell was.

In 2267, he provided a refuge at his house for a landing party from the USS Enterprise when they sought to escape the mayhem of the Festival, and later led them to a safe haven. After Landru discovered and abducted the landing party, Reger was able to slip away; he was somehow immune to absorption. Although part of the resistance, when he was confronted with an actual attempt to end Landru's rule, he recanted and attempted to betray the landing party to the lawgivers. (TOS: "The Return of the Archons")

Reger was played by Harry Townes.
According to the Star Trek Encyclopedia (4th ed., vol. 2, p. 211), Reger owned an inn, and it was there that he met the landing party from the Enterprise.
