In the Dead Zones, where only the Spike Runners dare go, almost nothing can live. The creatures that do live there are ruthless survivalists, hardened by eons of evolution, its eat or be eaten. One of the most feared is the Graffter. A bit larger than a horse they hunt in packs herding their pray into the narrow canyons with ruthless precision. Hope you never see one, if you see two pray you have enough nytrix for your boosters.
