Goblin

Goblins are Winter Fae. They were among Mab's troops in Summer Knight.

In the Series
In Summer Knight, in the war between Summer and Winter Courts, Harry led his group of Werewolves and Changlings around the battlefield, in an attempt to stop Maeve at the Stone Table.

Among the Winter troops behind Winter's battle lines, were battered Goblins dragging their dead and some of their wounded onto the carrion pile that Sylphs were scavenge ring through.

Descripton
Harry describes them as lantern-jawed, burly humanoids with wide, batlike ears.
