Official descriptions[]


This beautifully patterned egg was buried close to shore.


Aww... It’s a cute baby dragon. It tries constantly to find bodies of water to sleep in.

And look! A large, ornate shell has grown over its back. It must be close to maturing.


Archelonian Dragons are large, sedentary dragons with spiked shells found in deep waters. Once hatched, these dragons make their way toward the nearest source of water and only leave to find larger bodies of water should they outgrow their current home, or to deposit eggs into a hole dug into sand or soil. Although Archelonian dragons are most often found sleeping at the bottom of their chosen home, they are still known to be dangerous—when awake, these dragons use startlingly fast reflexes to nab prey before retreating back to the depths to sleep. Most Archelonians prefer the sea, but a few have been documented in fresh water reservoirs. They are most active at night, as bright light tends to hurt their eyes.

Turtle penguins, hahaha 😂

I do! Here is my original first sketch of the spiky turtle boi. I also scribbled together a quick headshot of an Archelonian. They look kinda silly with their mouths closed 😆

Some tidbits that will eventually make its way into the Encyclopedia probably:

—These guys sleep A LOT. Most encounters with these dragons are just finding them sleeping at the bottom of their chosen territory, rather statue-like and still; not uncommon to assume the dragon has died, though if you stick around long enough you may see it eventually rear its head up to the surface to breathe (still asleep, mind you!).
—They don’t breathe underwater, but have incredible lung capacity and can hold their breath for hours (sometimes days for the older Archelonians). Most of their life is spent sleeping, and as these dragons get older, the longer their stretches of slumber. Moss, algae, and other water plants often grow over their shells, and it’s not unusual for mini ecosystems to establish around an Archelonian due to their sedate nature.
—When these dragons do wake, they are typically in immediate hunting mode; anything nearby is fair game, including other dragons and humans. Their ability to snap their jaws around unsuspecting creatures has made many wary of getting to close to an Archelonian even while asleep, as the speed in which they shift from sleeping to awake is unpredictable. Purposefully waking these dragons is quite foolish for this reason, as they are rather peeved to be woken unnecessarily.
—If you manage to catch an Archelonian while awake but recently sated, they make for interesting conversation as they enjoy discussing their dreams.
—They don’t care to share physical space with others, so the vast majority of Archelonians don’t keep mates or companions (though it does happen on occasion). When their instinct to mate triggers, they will then rise from the water and search for a mate for up to two weeks, after which time they return to their slumber if they find no mate. Females will beach themselves to dig out holes on the shore to deposit eggs before returning home.
