The sets I'm not so crazy about but the figures are very usefull.
The Willa figure to me is a classic Drow(Dark Elf) design with the black and red with a spider brouche. Perfect.

Her face is hard to use but that can be easily swapped out.
The bat lords I split into to "Bat" factions, one with the orange/black torso and black bat helm and the second with the gray bat helm with the black and gray armor torso. I like to think of these two factions as of the Drow(Dark Elf) race as well. They kind of give a "Transylvania" vibe to them.
The Fleur De Lis torso is another human faction. So, out of the Fright Knight line I made four different factions. It took some time to figure them out in this order but now am
very pleased with it. I think its fine that some don't like them, keeps the price lower on Bricklink.
