Supported by a number of hollow tentacles, a bizarre creature in the shape of a beating heart approaches. Its multiple chambers rhythmically throb in a constant & hypnotic fashion. No apparent sensory organs or other facial features can be seen.

A Cardio Organelle is precisely what it appears to be: an ambulatory heart, larger than an elephant. Although they are often connected to the Red Flow, which they help regulate, they are sometimes encountered traveling between tunnels, looking for a place where their unique blood-pumping skills are needed.

The tubes that they use to intake & expel blood are the very same tubes that they use for walking; they merely seal the ends, & they become serviceable tentacles. Their large, roughly spherical body lacks any major features other than the tentacles, & the creature’s core houses a four-chambered heart (2 atriums & 2 ventricles, just like a human heart).

A Cardio Organelle is about 20’ across & weighs about 7 tons. It speaks no language, but it understands some Corpan.

• Blood Drain (Ex): a Cardio Organelle that has successfully grappled an opponent deals 1 point of Constitution damage per round; the Cardio Organelle adds all Constitution damage dealt by this attack to its own Constitution score for 24 hours

• Blood Fever (Ex): once every 1d4+1 rounds, a Cardio Organelle can inflict an excited state in an opponent with a successful touch attack; this effect is randomly either: confused, panicked, or a rage-like condition (+2 bonus to Strength, a +2 bonus to Constitution, and a +2 morale bonus on Will saves, -2 penalty to AC, cannot use spells, patient skills/feats)

• Improved Grab (Ex): to use this ability, a Cardio Organelle must hit with a Slam attack; it can then attempt to start a grapple as a free action without provoking an attack of opportunity; if it wins the grapple check, it establishes a hold & can Blood Drain

• Regeneration (Ex): fire & electricity deal normal damage to a Cardio Organelle, while all other damage is halved (50%); if a Cardio Organelle loses a limb or other body part, the lost portion regrows in 1d8+2 rounds; critical hits cannot be regenerated

• Transfusion (Ex): a Cardio Organelle can transfer any temporary bonus to its Constitution score (such as what is gained via Blood Drain) to any living creature it desires with a successful touch attack; these bonus points last for 24 hours, & can be distributed among as many creatures as the Cardio Organelle desires
