This hideous monstrosity looks like an enormous curled maggot, varicolored like deeply bruised flesh. Three flailing tentacles adorn each side of the thing's huge, pulsating mouth, and five more arch from its hindquarters.

Three times per day as a standard action, the Blood Queen may psychically link to up to 23 Hit Dice of kuru within 100 feet of either itself or one of its kuru surrogates; it may choose which specific kuru it would like to affect with this ability, but HD that are not sufficient to affect a creature are wasted. Any kuru linked to in this way must succeed at a DC 28 Will save or be forced to carry out the Blood Queen's telepathic commands to the best of its ability. In addition, a linked kuru gains a +4 morale bonus to Strength and Constitution and is immune to mind-affecting effects. The blood link lasts for 1 minute or until the Blood Queen ends the effect (a free action). When the blood link is broken, the affected kuru takes 1 point of Intelligence damage and cannot be linked to again for 24 hours. The save DC is Charisma-based.
Three times per day as a standard action, the Blood Queen can release a terrifying bellow that affects a 30-foot-radius spread. Any creature within the affected area must succeed at a DC 34 Will save or be paralyzed for 1d4 rounds. The save DC is Charisma-based.
In addition to its blindsight, the Blood Queen can constantly see and hear through its unholy kuru surrogates as though with a permanent clairaudience/clairvoyance spell. If at any time one of the Blood Queen's surrogates is killed, it is dazed for 1 round.
Whenever the Blood Queen swallows an unconscious humanoid or renders a humanoid unconscious with its swallow whole ability, it moves the victim through its digestive track, where the victim no longer takes damage, but rather begins to gestate within the Blood Queen's transformative stomach for 1d4 rounds. After the creature has finished gestating, it is regurgitated from the hindquarters of the Blood Queen, encased in an opaque mucous pod. Any attempt to remove a gestated humanoid from its pod causes massive system shock, and the humanoid takes 6d6 points of damage unless it succeeds at a DC 25 Fortitude save or those releasing it succeed at a DC 25 Heal check. As a swift action, the Blood Queen can send strong telepathic emanations to any pod within 100 feet, causing it to violently explode. The resulting spray of bilious ooze deals 6d6 points of acid damage to the creature encased in the pod and to any creatures in a 15-foot-radius burst.
Alternatively, the Blood Queen may allow an encased humanoid to continue to gestate for at least 24 hours, and after that duration may release the fully metamorphosed creature from its pod at any point. When released, the victim completes its transformation into a kuru surrogate. The Blood Queen may create any number of pods, but can only possess up to six kuru surrogates at any one time (if the Blood Queen releases a seventh kuru surrogate from its mucus pod, the oldest surrogate immediately dies no matter where it is and the Blood Queen is dazed for 1 round). The save DCs are Constitution-based.
