One thing we have learned from the desecrators of the dead is that very specific conditions are required when raising the undead. Our Agents have discovered the burial mounds of the tribesmen and to ensure they do not join the ranks of the necromancers you are going to consecrate the ground and destroy and lingering dark magic. Take this bottle of blessed wine and simply pour it on the mounds located by our Agents. I expect some form of resistance but you have already proven yourself quite capable. Dahim'el Yu-set Traveler.
