Six-legged arachnid-like creatures as large as a wolf, Racknees are the most abundant of the Horrors to come through the gate. Extremely fast runners with a vertical gaping maw bristling with dagger-like teeth, Racknees attack in waves, overrunning their prey and swiftly tearing them to shreds. They are exceedingly cruel, usually crippling their prey by tearing a couple large chunks of flesh away and then moving on, leaving the wounded man or animal to die of blood loss. They are the locusts of the horde, slaughtering humans, livestock and wild animals alike, their depredations have rendered most of Europe devoid of animal life.
Massive, vaguely-canine abominations as large as an adult grizzly bear, devil dogs have exposed bone structures protruding from their backs, giving them a skeletal appearance. The rest of their bodies are sinewy and hairless. They have muscular jaws and mouthfuls of sharp, jagged teeth. Despite their canine appearance, devil dogs are not pack hunters and will, in fact, fight one another over a kill. Their appetites are prodigious, they have been known to consume an entire human corpse in under ten minutes and begin hunting again almost immediately.
The most intelligent of the extradimensional horrors thus far observed, widowmaker demons are enormous slug-like monsters whose upper bodies are encased in an armoured carapace. Anchored to this armoured shell are two large arms ending in huge pincers capable of snapping a man in half. Even more distressing, behind the disturbingly human-like visage lurks a sophisticated brain capable of both advanced cognitive function and psychic attacks. Fortunately, widowmaker demons are relatively rare, but even one in a region can make human existence extremely perilous.
When fighter pilots first engaged in combat with helldragons, they described them as great flying worms larger than B-17s and with flight characteristics that defy the laws of physics. Little did they know at the time that the flying worms were nothing more than expendable larvae. Adult helldragons actually look like giant anemones hundreds of feet across. Adults constantly spawn larvae which are launched into the sky to fight amongst themselves or with anything unfortunate to come within range, typically about a hundred miles. Mercifully, the vast majority of helldragons die before reaching maturity. It is estimated that there is something like 50 to 100 adult helldragons scattered across Europe.
