The Tremen are a race of trees that show sentience and even mobility in some cases compared to normal trees. They all have faces on their trunks, and the position and facial features are all different for each Tremen. Instead of eyes and tongues, the Tremen have holes in their faces that make the eyes and the mouth. It can be hard to tell what they’re looking at because of this, but they can move their bodies to orient in the direction they want to face, as well make normal human expressions. No one knows how they can see without eyes though. But it does allow small critters like Squites or chipmunks to enter their bodies and live in them. Most Tremen don’t mind though, as long as they are friendly company. The leaves of the Tremen act as their hair, which some of them can style to mimic human hairstyles. They like to refer to their leaf hairdos as “leaftops”. Not every Tremen has a leaftop though.

Strangely their shoulders are positioned above their face, and their arms reach down as far as their roots. Each pivot of their arm is made like a mannequin; a round end that fits into a hollow bowl-like end to allow for flexible movement. However, it’s worth noting that not every Tremen are born with arms. Some aren’t even born with legs.

Speaking of, some Tremen are born with a pair of smaller trunks with shorter roots that serve as legs. This allows them to move freely whenever they like. Which Tremen are born with or without legs can’t be predicted, and is most likely random. Because of this, some Tremen believe not having the ability to move around is a curse, and this might lead to a lot of discrimination.

Tremen are genderless. There isn’t any kind of anatomy distinction to decide whether a Tremen is male or female, and thus it is concluded that they are androgynous. Even if a Tremen’s facial structure or leaftop style could portray them as a certain gender, that does not mean they are of that gender. Because of this, every single kind of Tremen has the ability to reproduce.

And they do this by eating a special kind of seed; one that can grow into a large acorn that hangs from their branches. Although there is still a chance that the seed might not fertilise a Baby Acorn. So, a Tremen eats as many of these seeds as they can at once to get a greater chance of bearing a Baby Acorn. Tremen can obtain these seeds from Squites, whom will mostly give it to them after some kind of exchange, like money in the form of nuts and berries. And some Squites give it to them for free. Whether they cost the seeds or not is dependent on certain factors about the Tremen recipient, like for example where they are positioned. Since some Tremen can’t move and there’s already too many trees around them, they might have to pay to cover the spacing fee, as well as child support since Squites are tasked to care and nurture the Tremen to proper health constantly.

When a Baby Acorn is born, it hangs onto a Tremen’s branch until it grows big enough for it to unlatch itself from the branch, and then dive bottom-first into the ground, where its roots are planted to help the Baby Acorn grow into a Tremen. During their period of Branch Hanging, the Tremen host – if they have to ability to move – looks for a proper place for their young to plant themselves before they unlatch themselves from the branch, because since there’s a chance the Baby Acorn could grow into a non-mobile Tremen, they want to make sure the place where they will spend their lives is a nice one. Fortunately, Baby Acorns are very bottom-heavy, and also have very sharp percaps for them to drill into the ground, so it is unlikely that they will miss the mark and not be able to plant themselves properly. Once they have planted themselves, after a short period of time, the wooden cup around their tops cracks off, allowing their branches, as well as their arms, to grow. This is considered the phase when they become Tremen Toddlers.

Squites have the main job of properly caring for the Tremen to stay healthy. Because since Yanside is set in a purgatorial dawn state, they don’t get enough light for them to photosynthesise, especially in darker areas where the light has trouble reaching. Some Tremen can survive on their own, particularly the ones that can move, as they can relocate to areas with more concentrated light, and absorb moisture and nutrients from the soil. But other Tremen are not so lucky, and thus Squites have to care for them to make sure they don’t die.

Tremen have the innate ability to communicate with other Tremen that are any distance away from them, even if they are on different sides of the planet. This is because their roots not only allow them to absorb nutrients and water, but also information of what they see and hear. And in turn, they can pass that information to any other Tremen in the world. This makes them perfect for messaging, and for faster communication of world events. Basically, think of it as like the underground Internet for trees.

Tremen also act as the historians of Yanside. Because of their longevity and large capacity for knowledge and memory, they are able to evoke near-accurate tales of old to inspire future generations, on top of having a root network to absorb and convey information really fast. The older a Tremen gets, naturally the more information they have to say. However, even Tremen are prone to senility. And in turn this can muddle up the tales they’re talking about and can inadvertently spread misinformation. Not to mention, they can be a bit boring to listen to.

And let’s not forget the other main reason why they are important to the world… oxygen. Like regular trees, their ability to absorb carbon dioxide and reproduce it as oxygen keeps everyone on Yanside breathing.
