The wraith is from the Lord of the Rings range, a barrow wight. It appealed to me as far less cartoon like than the usual robed skeleton with scythe. At first I was going to paint it black robes and armour to match the vampire, but decided on ghostly glow in the end, to further reinforce that it is a wraith and not a wight (though I reckon it could be used as either if need be).
The army feels more complete now. The vampire is the general of course, with the wraith her personal bodyguard. She also has three necromancers in her thrall, who she uses to resurrect and control her skeletons, zombies, ghouls and grave guard. The varghulf adds some much needed punch. That adds up to well over 1500 points and I think it could be fielded in a small battle. I also have a corpse cart and dire wolves painted, I want to spruce up the former while the latter I am hoping to replace. There is still plenty more to come with the army, including cavalry and flying contingents, plus more skeletons and some ghostly additions. As ever, finding the time to fit all these things in among my other projects is the biggest constraint.
