making a little guy (lore dump)

now that cadogan and his little guys are their own things i can explore freely, i want to talk a little about how they're made. lore subject to change of course, but the general idea i'm working from atm...

the in-universe term for what they are is "chimeric homunucli", but for ease i usually refer to them as cadogan's servants. they are not familiars. familiars are different. the three most basic components a chimeric homunculi must have are bones, blood, and semen. other elements can be added to better determine the form of the guy, but you won't get anywhere without those three things. bones are the scaffolding on which the body is built, blood forms the flesh, and semen provides the spirit. all three of these will have some effect on the personality and behavioral traits, but that mostly comes from the blood and semen. the blood imbues instincts, semen imbues intelligence and creative thought.

cadogan prefers to use gnome bones as his base because they're easy to get and because they make his creations conveniently pocket-sized. it's easier and safer for him to only make them big when necessary, with magic. for one thing it would require Significantly more material to make a full-scale creature, which is difficult to acquire and properly prepare. for another, they're much harder to control when big. obviously. if they were big all the time he'd never get anything done.

madog's basic components are gnome bones, manticore blood, and goblin jism. the manticore blood is where he gets his aggression and territoriality, and much of his strength when big. the goblin jism gives him the ability to think rationally and understand commands, and also the ability to work as part of a group. you'd never think it, but he's very good at teamwork. altogether he's a dedicated, completely loyal servant who'll take to tasks with vigor and gusto. good for a brute fighter to send out in times of trouble. he'd defend cadogan to the death.
he also has manticore hair and imp wing membrane. these don't have any real effect on his personality or behavior, and are purely functional. the hair is to give him his fluffy appearance, the wing membrane is so he can fly.

myrddin's components are again, gnome bones, but also sea serpent's blood and troll jism. the sea serpent's blood attunes him to the water, giving him his hydrodynamic shape and skill at swimming. it's also given him patience and the instincts of a hunter that rarely feeds. he's not overly quick to action. the troll jism provides a greater intelligence than the goblin jism, closer to the level of a human. he is a much more rational thinker than madog, able to slow down and think fully through a problem rather than rush in to meet it.
his secondary components are serpent fin and mermaid hair. these are almost entirely aesthetic, but the mermaid hair Does make him silky smooth to the touch and keeps wild animals from attempting to eat him.

and that's most of what i've thought out! before anyone asks, human bones + human blood + human jism would create an undead abomination and We Don't Do That. human blood and jism are alright to use but human bones are a taboo that crosses into necromancy. human wizards care less about the personhood of tailed species, so that's more okay (though it isn't really)
