This topic shouldn't be in the "Alien Colonists" part of the boards! Grr! Jeremiah is a hybrid, better to put him under "The Syndicate"!
The Jeremiahs were cloned hybrids like the Samanthas, the Gregors or the Kurt Crawfords. They are the products of experiments on hybridization that the Syndicate decided it would be best to put to use than to destroy: they're used as labour force in various tasks, such as updating SEP and medical files in Social Security facilities... More about Jeremiah on my website.
Edit: err...no, it's not on my website *yet*! I just realized that I haven't uploaded anything regarding Talitha Cumi/Herrenvolk. I'll take care of that shortly.
