A hostile race discovered through dimensional boring. The first encounter with the violent and nomadic Tarxan occurred in Neo-Constantinople of the Eurasian Alliance, hence the Turkish/Central Asian rooted name.
"The perfect pet at the perfect price -- guaranteed." Creature Dex at the bottom of the sub, if you want to include "relatively harmless" alien critters in your campaign.
A blue green jewel, Beta Delphini II, home of the turtle like Chelonians. The world is old, and bears many scars, the craters from orbital bombardment and high power explosions, rings of dust and debris that were once starships, habitats, and fighter craft. But the world below remains tranquil, its wounds covered with blue seas and green forests.
A member of the Cynopterid race
This humorous short fiction piece was inspired by a late night chat with a couple gamer friends about how alien cultures would possibly interpret some of the more "colorful" aspects of our society.
The party has found the source of the strange creatures roaming the countryside. The rift in this reality glows with a silver hue, rippling with the wind but never moving. They step through and are immediately assaulted with the scent of rotting meat, some have to muster all their strength not to vomit. Strange cries similar to the beasts the party had faced before can be heard in the distance. Looking around, they see they are in a forest of grey and red rather than the normal brown and green. The trees are sticky to the touch and writhe, perhaps to get away or perhaps as a warning.
The deeper the party goes, the more the forest seems to slither and move underfoot. The cries get closer and more numerous. Creatures lurk in the shadows, all the same color of their surroundings. Whatever the party came in here for, they had better do it fast.
The forest of flesh is waking up, and it is so very hungry.
