Loki Lekkman is one of King Pikko Vainola's leading cronies. As per Marika Pellervoinen:

Loki Lekkman is a dwarf from old Brevik. He has a floor of rooms in the Green Tower where he supposedly does horrible things, and he is known as being the cruelest of the King's advisors - and probably his favorite. If he were killed, few beyond the king would care. When not at the Green Tower, he has been known to bring his "wrecking crew" of men, dwarves, and elves to the Flagons or the Red Ogre Inn.
