Ogat
Ogat was an inhabited planet in the Ogat system, in the Beta Quadrant.

In the 24th century, this Klingon planet was home to a training academy, where young Klingons studied the way of the warrior. The academy course was difficult, but the teachers were excellent. 

In 2370, K'mtar suggested that Alexander Rozhenko should leave his father and attend the academy on Ogat in order to better train for a warrior's life. Worf ultimately refused, and Alexander remained on the  a while longer. ()
