Cave Mouth
A Cave Mouth is a living creature that inhabits a cave, then forms into a false cave interior. It makes itself look inviting for animals or sentients to seek shelter in. Once an creature is inside it, it collapses around them and digestion starts. Unless one has access to some magical spell that will injure the Cave Mouth, escape is impossible and death is quick.
In their natural state, Cave Mouths are large gray blobs. The biggest can be the size of a house. Cave Blobs only digest living flesh & bones, so any cave they use is often a good source of items they couldn’t digest, including weapons & armor.
Cliffworld
In the universe of Earth 101, the planet Mars has more than one huge canyon. In fact, it has 5 of them, the largest going down nearly 3 miles and extending more than halfway around the planet. For centuries, Mars has been known as the Scarred Planet. However, people who live on Mars call it Cliffworld.
The 3.5 million people living on Mars make their homes in the sides of these great canyon walls. This is made easy because most of the canyons of Mars are riddled with caves, some up to a half mile wide. The largest cliff city on Mars, New Chicago, has a population of 125,000 and occupies 13 interconnected caves. Most other cities run between 20,000 and 75,000 people.
Transportation between cities is done with airships, although some daring Martians like to travel in the large spidery robots knows as “cliff crawlers”. Such travel is not for the fainthearted.
The most flowing water on Mars is always found at the bottom of the great canyons and it is here that you’ll also find a breathable atmosphere. All of these canyon floors are Planetary Parks and are the first areas to be fully terraformed. The rest of the planet still has a century or so to go before terraforming is complete.
