Here is my first attempt. It seems out of the ordinary in comparison to the others, but it said it could be any form... And I'd like to try this style out. Also... Apologies, I did this on mobile. 3am and... Sorta resting?
Casseena - The Spider Queen. Keeper. Casseena had been around for a long time, experimenting with humans and ways of creating a brood. Ways that would not require her to lose focus on her surroundings and leaving herself wide open. Not exactly creating broods, more like... Producing. For a time it seemed that she required human bodies to mold her home... And feed her home. Her appearance is that of a massive drider. Not that of an impossible size, but in comparison to nearly that of a trebuchet. Any Constructs she had in mind to create were to only be driders and only the size of a horse and carriage. It was due to her size that she was afraid of doing much more than reproducing, using live hosts as breeding spawns of her spiderettes, but because they were so small, the hosts, she would barely get more than a max of two. Which is why she settled down, literally, and stopped grabbing random travelers. Because of her size, she couldn't fit into many places. Due to this, she burrowed into an underground crypt, and stayed with her heart in one place, protected by earth and stone, she'd make her spiderettes do the work of capturing humans, forcing them to work, and devouring them when they became to weak or sick. Now having the ability to reproduce them with her own body. (Strength, slight speed, breeding appendage similar to that of the Alien Queen from Alien/Alien vs Predator)
Spiderette - Massive spiders in comparison to your ordinary household pest, as big as dogs and nastier than a rattlesnake combined with a rottweiler. Nasty bites, paralyzing poison, strong like ants, and hardened webbing make them perfect human-snatchers. But because they seem to like only eating what they were made to catch, having too many would starve them since a lot of what they capture need to be used as slaves. Still as squishable as a giant rat, but the exoskeleton defends against most substances.
Dungeon - The Hive, an underground crypt which has one or two rooms from the main crypt, which aren't large enough to serve anything beneficial except a place to drop skeletons and the other to hold the heart. The place is covered and filled with hardened webbing (strong like plastic wrap only a lot harder, denser, and not easily cut. Not resistant to fire), and stickier than superglue (dissolves by spiderette saliva). The dungeon is currently trying an intimidating scheme, rather than a ready to defend stance.
