The morakos (plural: morakoi), or "shadowkiller", is a carnivorous mammalian predator native to the mountainous regions of Daros IV, an Orion colony world.
It was the size of a lion and had dull black fur that melded completely with the shadows made by Daros, a bright, white sun. They used this camouflage to hide beneath overhanging rocks and ledges in wait for prey, from which they pounced onto a victim's back, pinning it with its weight. They then clawed their victim and tried to break its neck.
The morakos was known for being completely silent when hunting and even while attacking.
The Orion privateer built by Daros IV's Kerav Family was named the Morakos. (FASA RPG module: Orion Ruse)
