An Eidolon's Guide to Mythos

Isle of Fog

An island covered in an eternal fog. The island has no people living on it, and many of the creatures that live here are extremely shy and quick, so you most likely will never see them. The few that are aggressive have terrifying silhouettes and are extremely deadly. One should always be on guard on this island, despite the fact that very things are hostile. However, often it is not the creatures in the fog but the shadows upon the floor that take many a life, for those shadows are the pitfalls that this island is famous for.
Flora
Grass - small green plant
Fauna
Natural Animals
Ghost Fox - a pure white fox that people consider to be magical, as it seems to vanish into mid-air. Of course, with the island being covered in a thick fog, just about anything can vanish
Tibbar - a creature that appears rabbit-like, but has a few differences. It has long ears that seem to have hands on the ends of them, and a long, fluffy tail. They move around like rabbits, however, and are arguably one of the friendliest creatures in Mythos, walking up to you rather than running away
Amarok - a creature that appears to be a large, grey wolf. They tend to hunt solo, unlike normal wolves
Magical Fauna
Wraith - a creature that has varying appearances, but always has the same basic idea of killing you
Rage bug- a small, red beetle that is almost unnoticeable unless you are extremely observant. If it were to bite you, you would be consumed by a blind rage that would last until you either died or passed out from exhaustion, preferably the latter. Other variations of the beetle instill fear, arrogance, or even sorrow, and sleep is the only known cure. That, or wait it out. Various toxins can actually be made from extracting the venom of these beetles
Asobibi - small invisible tendrils that reach out and grab you, hindering movement. However, if one has an animal's senses or bears a light source, they become visible
Titans
"Mother" - a titan form of the wraith with a fixed appearance. The creature looks like a tall, skinny woman with disheveled hair, and glowing white eyes. Usually all you can hear is an unnatural ringing/screaming noise, but on occasion you can hear it say things that a mother would, such as scolding you for running away. "She" is also attracted to sound, especially the shattering of glass or laughter
