The master of the passenger vessel Astral Queen, who at Kirk's private request skipped his 2266 stop at Planet Q so that the Karidian Players would have to travel on the Enterprise.
Captain Jon Daily commands the Astral Queen, the ship due to carry the Karidian Players from Planet Q to their next engagement in the episode The Conscience of the King.
After the murder of Thomas Leighton, Kirk wants the troupe aboard the Enterprise where he can watch Anton Karidian. He calls Daily, evidently an old acquaintance, and asks him to pass Planet Q by without picking the company up, promising to explain another time. Daily agrees without fuss.
The favour leaves the actors stranded and allows Lenore Karidian to ask Kirk for passage, which is exactly what he intended. Daily is heard only over the communications channel and does not appear on screen.
