There is a certain poetry in death that few can read, but for those with the ability and the willingness, eternity is the reward. Eternity and perhaps their own personal bodyguard of undead slaves; but what good could those temporary husks of life have been to their owners anyway, if they did not have the vision to embrace the grave?
The Resurrectionists are about all things undead, and tend to favor summoning new models and raining debilitating effects (particularly Poison) upon their opponents. Their summoning abilities, combined with having lots of wounds and a lot of damage-mitigating abilities, make them very resilient (the majority of their minions are either Incorporeal or have Hard to Wound). However, with some key exceptions, they don’t have a lot of options for dealing death from a distance.
