The Magma Borer is a large creature native to the extreme world of Crematoria. Scientists and planetologists have yet to be able to explain so many things about the planet and the unknown lifeform that made it possible.
Your adventurers can name this one, if they survive. The last thing they will hear is: “ppppooockt-t-t-t-t-t-t-t-t-t” before their eyes and ears start bleeding and their body become black and blue… battered by something unseen and untouched.
On a world made entirely of molten rock, there is still life.
The Black Ones are a paranoid’s nightmare. They can take over any single body, or be hiding nearly anywhere. They can see as well in the dark as the light. They can hear nearly any sound, like the faintest heartbeat 10 paces away. They are totally alien, with motivations and drives that are nearly incomprehensable to humans. And the worst part is, they are here and you don’t know it.
Next time you're contemplating a horse variation, but don't want to get too dramatic, how about a Zorse? An offspring of a zebra stallion and horse mare. In nature they are infertile, but in a fantasy world, not necessarily. They are also known to be extremely cantankerous.
"It soon became apparent that zorses are not the most easiest of the equine family to get along with." -- Trainer Pat Parelli, on working with zorses
