Cruxites are dragon-like creatures that have different substances for blood, These substances can be anything from liquids, gases, fine powders (like sand) to more unusual things like fire, electricity, sound, light, darkness, etc! As long as it can somehow flow through veins it can be cruxite blood!

I only accept PayPal and points on DA

Here we can discuss anything cruxite related, like questions. 

I will regularly update information if any of the rules/info changes


Cruxite Rules (might edit later)


-all cruxites must have a substance flowing through their veins that is not normal blood

-the substance has to be able to move through veins and circulate throughout the body in some way

Examples of acceptable substances: Fire, sand, liquids, gases, sound, electricity, light, shadow, etc.

Examples of not acceptable substances: anything solid, string-like, large and chunky, like fabric, spaghetti, and beads.

Mixed blood: (rare) meaning the blood is not specific in it's type, and consists of more than one type.
examples- acid, molten metal, juice
This means the blood is made up of more than one type of acid, metal, juice, etc.
Mixed bloods are more likely to have genetic mutations and psychological disorders.

Non-mixed blood: (common) meaning the blood is very specific in it's type.
examples- sulfuric acid, molten iron, apple juice
So rather than just acid blood, liquid metal blood, or juice blood, the blood is specifically one type and one type only.

Genetic Mutations

- normal blood
(there is only one exception. Other than that one, no cruxites are allowed to have normal blood.)


There are no longer any rules on color.

P.S. I'm sorry if there's something that I forgot to cover or wasn't clear on, this is my first time selling and managing a closed species, so i'm still new to this. If anyone who owns or has experience with closed species has any comments or advice, please message me! Thank you, and I hope you enjoy Cruxites!

Cruxite origin

Cruxites were originally bacteria that drifted aimlessly through space, that evolved slowly over time as they mixed with different materials and substances. Once reaching a planet in an uninhabited solar system, which is is approximately 60 lights years away from our solar system, they began to evolve even further. After growing larger, changing form, and adapting to their new habitat, different bloods were created based off of the cruxite's diet, genes, etc. Different planets usually inhabit similar kinds of cruxite. For example, the closer to the sun the planet is, the hotter, deadlier, or more unstable the blood of the cruxite will be.

(is this okay? Please let me know what you think, and be sure to leave some suggestions and tips too!!)


Cruxite Example

My main OC, Twitch, is a cruxite. In fact, he is the first cruxite I ever made and it's thanks to him that I even created the species in the first place. He's an acid blood, which means that his blood is made of a mix of acids and not just one specific kind (like sulfuric acid for example. This means that he is more unstable than other cruxites that have non-mixed blood, both genetically and mentally. He is completely immune to things such as burns, poisons, and other acids because his body is made to withstand things like this. The more unstable a cruxite is, the more likely they are to have genetic mutations and psychological disorders. Twitch has something similar to manic depression, also known as bipolar disorder, which makes him more likely to snap and suddenly turn violent.

Blood: mixed (rare) acid blood

Mental state: unstable

Coloration:  black with bright markings

Limbs and tails: 4 limbs (common), 1 tail (common), bipedal (uncommon)

Head(s): 1 (common)

Wings: none (common)

Eyes: 2 (common) with pupils (common)

Head spikes/ears/horns: Mock ears (common) not part of skull (common)

Mouth spikes: yes (common) part of skull (uncommon)

Exposed teeth: yes (common)

Genetic mutations: changes appearance when angered


Im sorry if this is too complicated XC

Note: The mental disorder that I said Twitch has IS NOT actually bipolar disorder. IT'S SIMILAR, NOT THE SAME. Please don't kill me I wasn't trying to give anyone the wrong idea about the reel disorder I was just using is as a comparison to give everyone an idea of what I was talking about. Mental disorders are nothing to be joked about (trust me I know I have 3) and the last thing I want to do is spread false information.



Oh I love them. I have no money right now, but I'd totally buy one if I had the cash.


luxidoptera I'm so glad you like them!!! (hearing this made my day 100 times better no joke)

I just got this idea, but what if I made mini adopts that cost less than the regulars? Like maybe $5?


ZugZwang853 That might be a good idea!


luxidoptera Okay, i'll have a small batch done soon!



This character is up for adopt! Buyer can request a full ref. sheet, which can be custom.

Regular ref + character- $15

Custom ref + character- $20


A made a discord server for cruxites for anyone who's interested!
