Lost Eden/Nightmare Fuel

Plenty of it in this game.
 * The Castra tribe and their almost emotionless whisper start out as this. Their first act is to hold Dina hostage, and it goes downhill from there..
 * Moorkus Rex is a prime example, especially when you meet him at the end. He's one bloody (literally) nasty customer. What he does to Mungo, Dina's mate, is enough to make anyone shudder..
 * The Tyrann mooks were no prettier. They looked like mutated Utahraptors, and if you were unfortunate enough to encounter them in the field, it didn't end well.
