Elithia

Aeginian homeworld is currently Elithia (originally Earth/Terra), which is very similar to Earth in many ways. Similar climate, vegetation etc., so garden and forest worlds are the most like their homeworld.

The Gar-Aeroix is the planetary system in which Elithia is located. It's home to a couple more planets - including Icicle, the home planets of the Notix and Trink - but Elithia is by far the most densely populated planet in the system and the only one with an Earth-like climate.

Gar-Aeroix (Dremetonian for Great Planetary System) is the name for the planetary system as a whole, much like how we call our planetary system the Solar System. The star of the Gar-Aeroix has never been named, actually.

The moons of Elithia - Laena and Vaeda - are both colonized, though they don't house especially large colonies. The moons have very low gravity and are generally not a very pleasant/safe place to inhabit, but there are a variety of colonies on the two moons. Some of these are military bases, others are research facilities or mining operations, but there are also some luxury resorts and a bunch of other smaller colonies.

Timeflow
Elithian years are slightly longer than Earth years. A day has roughly 20 hours. On the whole, very similar to Earth time. Standard years are the years measured on Elithia, but those are very similar to Earth-years, with only a few days difference.

Plantlife
Thus far, most portrayals of Elithia have been shown to have plants just like Earth: various types of trees, bushes, grasses and more, which looked exactly like their Earth counterparts. In the canon, however, there are some more differences, although I'm still working on them a bit. There are trees, bushes, grasses and such, but their cellular structure is a bit different and so are their overall shapes and appearances. The farmable plants in the mod are a good example of this: they look familiar, but they are certainly different from Earth plants.

Wildlife
Elithia is home to some pretty strong creatures, but nothing too incredible.

The Aegi, Dremeton and Craton obviously stand at the top of the food chain, but that's because like humans, their technology and innovation makes them the apex species. If you only count wildlife, there's various wyvern-like creatures competing for the top spot on land and in the air.

There haven't documented any classes other than the wyverns yet, but there's many classes similar to those found on Earth (mammals, birds, reptiles etc.)

Kelbet
Kelbet are pretty much the Elithian version of deer.

Trangii and Taragii
The Earth equivalent of trangii and taragii would be dogs and wolves. The taragii as shown in that creature collection are extinct - they were the ancestors of the modern trangii - but other related species do still exist in the wild.

Faryth
Faryth are a form of wildlife found on Elithia. They somewhat resemble flying snakes, with long, thin and flexible bodies, and a pair of large wings. They're mostly found in the densely forested regions of Elithia, where they can use their camouflage to hide from larger predators and smaller prey both. They're quite fast, and are carnivores, mostly eating smaller animals but sometimes attacking larger ones too if they are weakened.

The Faryth are part of the Wyvernia class, named after the mythological creatures from Earth. There's a lot of creatures on Elithia that look a bit like wyverns, having two hind legs and two large bat-like wings. The Faryth have lost their hind legs over time, but are still part of the same class. Both the Faryth and the Farythian are primarily green, with some variation in the shade of green. There are rare mutations that make them white (essentially albinos), and some can be slightly brownish, but green is the predominant colour.

The wyvernia are lizard-like animals with usually a single pair of bat-like wings. Some of them have hind legs to walk on too, but many species only have a few small internal bones where the legs used to be and look more like flying snakes. The Faryth is the prime example for this, while the related Farythian species is a good example of wyvernia with hind legs. They don't breathe fire and aren't really anything like mythical dragons and wyverns, but they were named after the mythological creatures for their similar external appearance.

Both the Faryth and the Farythian don't stand any chance against an armed Aegi, but if you ignore modern weaponry they are both pretty dangerous. The Farythian is large, surprisingly fast and incredibly strong, and an unarmed Aegi wouldn't stand a chance against it. The Farythian is a predator at the top of the food chain in its ecosystem. The Faryth isn't quite at the top of the food chain, but it's incredibly fast and while it likely wouldn't kill an Aegi on its own, it'd definitely cause a lot of harm. Faryth often hunt in groups though, and against a group of them an unarmed Aegi (and sometimes even an armed one) is definitely in grave danger.

Both tend to keep away from civilized places though, so encounters are pretty rare. Farythians near cities are extremely rare, though Faryth do sometimes find their way into a city. They might attack someone if they feel threatened, but that's pretty rare.

Trivia
There was a race of desert-dwelling flying creatures that lived on Elithia called Hea-Hoans. They were created by Freddycatking, a former member of the THEA roleplay, but since he hasn't been active in the THEA community for a long time. The Hea-Hoans haven't gotten much attention and they aren't officially part of any of the current storyverses.
