On Helca, the mastery over Undead is controlled by the Lich Lords of the Fallen North; the pacts they make with mortals seeking power is referred to as the Cold Bargain. Using the stolen power of the god of death, they have mastered the “breeding” of the undead and animations. Technically they can exert influence and control over any true undead on Helca – at least until the specter lord unlocked some of their power for himself. The ability to do so seems to have driven the Lich Lords even more mad over time – the voices in their heads never stop and only multiply. Regardless, the lords of undeath have mastery over all and have been able to amplify slightly, their normal powers. It should be assumed that anywhere there are undead, that the Lords of Undeath will be able to see, feel, and hear from their presence.
The Lich Kings together can cause an animation or undead servant to carry the Token of Death. Upon striking an Extraordinary (critical) hit, this token is transferred to the victim – there is no save for living creatures of a normal order of being. The accumulation of these tokens make the target more susceptible to disease and poison effects, less likely to survive grievous wounds and many of the lesser mystical remedies for death’s door will cease to function.
The Lich Lords mingle their Essence and assume some control over their agents, transferring some of their power to them as well – this is The Cold Bargain. It requires the sacrifice of one or more sentient living creatures. It allows the Lich Lords to perceive through their senses. It creates a Mind Schism (Split Mind). As long as the embrace is functioning, they have Disadvantage on sanity checks.
