Iago

A very strange being, no-one is entirely sure what this creature is completely about...
It tends to present itself as a docile, friendly creature and will work itself into a household with little difficulty.
However, those it takes to following tend to befall tragedy shortly thereafter, which has given it a reputation of being a bad omen.

Because of this unfortunate trait, it has been dubbed locally as Iago, after the Shakespearean villain that used a guise of friendship to destroy his rival
(not that this creature itself directly causes said tragedy by its own means, but seems to move on once said tragedy has struck).

Although a mostly silent creature, it has a habit of shrieking at the break of dawn. And also at sunset.
Whether or not it has some connection with the cycle of the sun is unknown, but some believe so.
It appears to sustain itself on insects and small animals, and possesses a long tongue akin to an anteater.

Iago is currently living in the home of Elliot Armitage, who is the first human that hasn't kicked it out after a few weeks.
Because of this, Iago has developed a protectiveness over the skittish man and acts as his weird guard dog.
Usually he is about the size of any medium-large dog, but when angered or protective, he can grow to massive sizes.
Can also be seen occasionally floating and speaking in tongues.
