Marrowslugs
Description: a foot-long slug with a circular mouth on one end, with the requisite sawtooth fangs. Marrowslugs smell hideous, are grey-yellow in color, and constantly exude a somewhat toxic mucus that acts as a powerful sedative and hallucinogen. Marrowslug attacks are downright disgusting, and easily fatal if the victim isn’t treated in time.
Mad Science never really goes away; it just finds new and exciting fields of study to batten off of. And it doesn’t matter if the new field seems fairly exotic already. Like, say, genetic engineering; your typical Mad Scientist will just simply go farther into the Febrile Lore for the necessary inspiration. Mad Science is not really a rigorous scientific discipline, in other words. It’s basically a state of mind.
