General description-
Spoiler
The magi who first discovered these companions reported that they startled her quite a lot. Astacus dragons can grow incredibly large, and most adults are larger than a grown human. They move in a peculiar way when surprised, fleeing backwards using their legs and tails to propel them. Astacus have bright yellow eyes, and their expressions never seem to change, making it all but impossible to determine their mood. It is much easier to judge their current feelings through their actions. An angry astacus dragon won’t hesitate to snap their claws at their enemies, and chase after them. Most animals know to flee from these companions - their large claws are strong enough to sever most creatures nearly in two! It’s advised never to enrage an astacus dragon, as it is impossible to pry their claws apart. These companions can even cut through coral and some rocks, and their claws never dull and can be regrown. Astacus dragons are only found in the deepest waters of oceans and seas, and wild astacus dragons are never seen above water. They are secretive creatures, and very little is known about them. It is very difficult to find them, for they make their homes in dangerous waters, and their coloration helps them to blend into their surroundings.
A strange little creature has emerged quite a bit from this egg, but refuses to completely leave its shell.
Hatchling description-
Spoiler
These little ones are very feisty. They will snap at anything that catches their attention, and must be taught from a young age to be careful with humans. Most people give their young astacus dragons stuffed waterproof toys to hold onto, which comfort them and prevent accidents. Woe to anyone who dares touch any of these toys - astacus dragon hatchlings are extremely protective of them, and will pinch any offenders quite hard. It is a sign of great affection if one of these little ones offers their toy to a magi, as it is very hard to earn their trust.
I want a fox creature.
Or an Egyptian creature.
Piercing green eyes too.
