The Ryn, as their species is called, are anthropomorphic hooved mammals living on the world Ryndor. They have an average height of eight feet and have only been found with fur colors in shades of dark blue, purple, and green. They have two pairs of arms, each hand having four fingers. They also have antlers with a slight curve to it and four pairs of eyes. Two of which are pointed upwards while the rest are facing forward. Additionally, they have a slightly long tail and snout, the former of which has thicker fur on its tip.

This individual used as an example is much shorter than the former species, the common height of the species now being five feet. Though some can be around six feet tall, which is seen as the trait of someone that will be greatly impactful in their life. The coloring of the species is now diluted, having darker fur also being seen as a sign of fortune. As you might be able to see, any traits that are similar to what the species used to have are held in high regard. This extends to having four fingers on a hand as well. The amount of arms a Ryn has can vary of course but something that most of them have is that their hands commonly only have three fingers, having four being very uncommon. The Ryn have very curved antlers and have a varying amount of eyes, commonly having four or more eyes. And they also have a shorter tail and snout. Additional mutations can of course occur due to the lingering radiation.

(Both time periods have omnivorous teeth, and both of them have very cursed smiles whenever showing teeth. Also I was too lazy to make an accurate comparison of their heights)

*Future Crow here, I forgot to mention that the species is born without a sex. They have something similar to cloacas except they aren't used for reproduction. What I decided would be a good answer for how they make a baby is the following (don't worry it's just magic):

So there is a magical area in a small mountain where the planet's moon shines through the ceiling. Basically the gods that the Ryn believe in blessed that place so they can just use several individuals blood to magically form a baby. And here are some conditions or facts about how that works.

- All participants have to actually be in love in order for the spell to work

- It can work with two or more people as long as all individuals are, in addition to being in love, all of legal age where they are considered adults, no one is related, no ill intent is meant towards the child, the relationship isn't toxic

- So it works more specifically like this, two or more individuals are in love and want a baby. Well all they have to do is travel to the blessed location, each give a drop of blood on a stone from the mountain, then they close their eyes and wait for a couple of minutes. After they feel a chilly wind inside the cave they open their eyes and are greeted with an egg where the the stone once was, they have to take care of it for 7-8 months for it to hatch a baby made of the individuals' DNA. And then they raise it and so on.
