As of 2392, second officer Ja'rod viewed Klor as "overcautious" (something mention in Ja'rod's supplemental log). The captain refused to have the ship follow the trail of a possible Gorn vessel near Klingon space.
Klor was executed in 2396 (along with the ship's first officer) when he was overthrown by Ja'rod. This action was taken due to the captain's decision not to investigate Undine activity in the Rha'darus system. (ST website: The Path to 2409)
