I dont know the rules for bring back dead posts, or if there are any rules on necromancy... but I was able to just purchase a complete set of Heroquest with only 1 mini broken, If any one is still interested I can post pictures of the minis.
I used to play HQ with my brother so my figures are not in the best of health but I believe the whole set is there still, in fact I've just looked behind me and I can see the box sitting at the bottom of a pile of stuff I took out of the Utility room
Getting back into the thick (or rather thin as in thinning my paints) of it, not picked up a brush in some time so this may hurt a bit until I get used to the feel of them again
