Masked Gnome
From Sourcebook Wiki
The Masked Gnome is a mysterious entity who inhabits the foothills of Kred. He is noted for ambushing caravans of kobold slaves and killing their keepers, and more recently for sneaking into the depths of Kred to free the kobolds there.
He commonly dresses head-to-toe in black leather, and makes use of an exotic repeating crossbow.
