DEVIL'S GUTS [Dirofilaria Daemonium]
FIG 1. :: VASCULAR CENTER - The parasite imbeds itself into the heart on the host. Due to the quasi-immaterial nature of the vines, this seemingly lethal blockage eventually causes some cardiac-related symptoms and yet does not result in immediate threat to the host's survival.
FIG 2. :: KNOWLEDGE - The parasite is categorized as a Daemonium (demon) rather than an Aegritudo (affliction) because it is sentient and communicates with its host through visual, auditory, and tactile hallucinations. There is debate on whether the brain is the true first target of the parasite, rather than the heart, as the first symptom of an infection is the intense sensation that one is no longer alone.
FIG 3. :: INVASIVE SPREAD - The parasite uses the vascular system as a guide to infect the full body, but as infection progresses it can expand beyond and wrap around, into, and through all structures and systems. Similiar to the plant named after it, the parasite will eventually smother the host.
