History
1993
In 1993, Albus Dumbledore hired security trolls to guard the Fat Lady's portrait after Sirius Black attacked her in an attempt to get into Gryffindor Tower and Sir Cadogan was fired for letting him in while was covering for the Fat Lady. These Trolls were placed in the North Wing and were evidently a different type of Troll than the mountain variety, since they seemed considerably more intelligent and less smelly. They spent all their time pacing the corridor in front of the Fat Lady's portrait, giving dirty looks to everyone who happened by and comparing the sizes of their clubs.
1996
In 1996, Dolores Umbridge apparently also hired security trolls to guard the Harry Potter's Firebolt after she confiscated it and banned him from playing Quidditch.
