Camp Kaboom

Camp Kaboom is the unofficial nickname of a desert training grounds used to train young potential wardens in combat magic.

History
Although Harry Dresden never visited Camp Kaboom during one of the books, he did have a flashback of a visit during the narration of White Night. During this flashback, the camp was ambushed by a few Ghouls, and two young warden trainees were abducted.

When organizing the rescue attempt, Harry interrogated two captured ghouls to determine where the two trainees might have been dragged off to. This is significant because Harry had to use Lasciel's shadow as a babel fish due to the ghouls only understanding ancient Sumerian. This apparent fluency with "Ghoul" despite Harry's well known issues with Latin was also witnessed by several wardens garnering some uncomfortable questions later.

Unfortunately, the rescue attempt was unsuccessful and by the time Harry got to the trainees they had already been killed or mortally wounded and partially consumed. This event seems to have affected Harry so severely that he "hates the creatures with a passion so pure it's almost holy", and the ensuing wrath that he reigns down on the captured ghouls is so rage filled and brutal that most of the onlookers are left aghast and full of fear.
