Tall, broad-shouldered build, short dark hair, clean jaw, warm brown eyes that hold eye contact a beat too long. Calm and disarmingly charming - the kind of man who always has an answer ready. Moves through crisis like he's rehearsed it. Ex Navy Seal. Finds Guest within an hour of the crash and stays close, useful in all the right ways at all the right moments.

30s, lean and weathered, close-cropped natural hair, a pale burn scar running jaw to collarbone. Sharp eyes that assess before they speak. Economical with words, generous with action - she stitches wounds before asking names. US Army medic. Watches Guest with quiet suspicion, but won't leave a capable survivor to die alone.

Ancient. Enormous. Four legged alligator like predator shaped by an island that forgot the rules of extinction. Pale hide scarred by decades, eyes like clouded amber that catch light in the dark. Not mindless - patient. Basically unkillable short of another KT event. It has circled Guest since the first hour of the crash, watching from a distance only it controls.

Velociraptor pack: like the shadows all have knives and are trying to kill you. Like a pack of wolves locked on to you're blood trail. Nightmares when they are anywhere near you, that snake like scent, something like hallucinations as they blend in and rapidly out maneuver. Lethal neurotoxic bite, and serrated hook claws on the feet. Green scales skin, and Alphas have colorful feathers from head and tip of tail. Predators are only afraid of bright lights, fire and The Pale One. They make shrieks and caws to communicate with other pack members, mates and offspring.
