"Make sure you tell all those humies, humie, make sure you tell ’em good, make sure you tell ’em about the king in da mountain. Tell ’em all about me, Skarsnik, tell ’em all about my life, leave nuffink out."
- —Skarsnak, Night Goblin Warlord of the Eight Peaks
Sinister Tribe's of the Night Goblin's
Night Goblin's are a sub-species of the Gobliod race, who's very existence is mostly spend in the dark and damp undergrounds of the World's Edge Mountain's and many other places. These creatures of the night, mortally hate the sunlight and any source of light, perfering to live in near total darkness. These creatures are adept in night time fighting, often having better eye's then most land-dwellers. These Goblins are only known to leave their caves and hideout's only if the sun is setting or down, and when there is little to no light. Those who do come out during the sun-light, they would often wear dark clothings or plain black robes, for the sun-light seems to hurt or burn the Goblin's skins. The most famous Night Goblin Warlord is Skarsnak of the Eight Peaks.
Overview
Creatures of the Night
Many years ago a tribe of Goblins took to living in the caverns and tunnels of the World's Edge Mountain, and there they lived in total darkness, wearing pitch black clothing and taking up the name of Night Goblins. Night Goblins have become so accustomed to the darkness of the caves that they mostly only move during the night, and hide in the day. These Goblin's have a higher sense of sight during the nightime, making them expert's in night-time warfare and ambushes. Many of these Goblin's wear their distinctive black or dark colored clothing's that cover as much of a Goblin's body as possible to hide their skin from the hated sunlight. The Night Goblin's are a more fiercer tribe of Greenskin's then their related Gobliod cousin's, due to the fact, that most of their tribe have a strong sense of independence, and many of the Night Goblin's tribes, have mostly Night Goblin's in their ranks.
Night Goblin's are well suited to their subterranian life, where they range in size, but many are in the stunted side, which better suit's the enviorment they live in. Night Goblins are easily marked out from other greenskins as they wear long, dark and hooded cloacks, in part to blend in with the poorly lit tunnels, but mostly to protect themselves from the hated sunlight should they venture above ground. Given a choice, NIght Goblin's would almost never go above ground in the day-time, unless it's shourded by darkness or cloudy. When they do emerge, Night Goblin's lauch deadly raids, and ambushes against travellers in the mountain pass, and commit countless other malicious deeds. Indeed, due to their proximity to the mountain caverns and tunnelway's, they are considered the mortal enemy of the Dwarven Empire of Karaz Ankor. While mighty WAAAGH!'s have been pushed back time and again, in the land's above, those hold's that fell during the Goblin War's and many ages past, were due to the attack from these creatures, where the cavern's allow whole hordes of Greenskins, and monsters alike to invade the depths of the Dwarven Hold's.
In the moist darkness of their subterranean lairs, the Night Goblin's are inundated by all manner of moulds and mushrooms. Many kinds of toadstool are grown for variety of uses. Fungus is consumed, mixed in potions, used as medical treament, used to fuel glow-lights and used as baid to attract unsually creatures known as Squig's. Night Goblin's are especially cowardly, but unlike those of other Goblin clan's, Night Goblin's create a special brew called Fungus Beer, that enables their brethren to fight in a near maniacal state, where they are completely insane and paranoid, and would enhance a Night Goblin's sense and reflexes, to fight better against other stronger foe. Perhaps it is the lack of sunlight or the proximity of so much dank mould and mushroom, but Night Goblin's still produce more buldging-eyed lunatic's than all the other Goblin tribes combined.
Displaying even more than the usual goblinoid lack of common sense, individual Night Goblin's gleefully ingest dangerously hallucinogenic mushroom. Deep in their caves, Night Goblin's shaman's are one of the most feared Goblinoid shamans in the World's Edge Mountain. Not only are they powerful magic user's, they are also expert brewers and cultivators on mushroom's. These Shaman's grow and cultivate these mushroom's in order to create the infamous Night Goblin brew's that make's the Night Goblin's into crazed pycho's. When a leader arises who is sneak and cunningly brutal enough to focus the boundless energy and spite of the Night Goblin's, he can wield their number's as a formidable (if unstable) horde. When the tribes are called to war, the mountain's are littered with holes, each issueing forth a steady procession of cackling, black-hooded Goblin's. Horrible high-pitched shrieking issues forth from the caves as does the unpleasant smell of fungus-beer and mouldy rot. The army cluster's in the shadow's gathering in mobs beneath their tribal banner's. Should the moon emerge to light the vales, it would reveal a nightmare, a teeming mass of Night Goblin's appear out of their hideouts. Although individually weak, Night Goblin's rely on number's and brute force to win. Archer mobs unleash hails of arrow's at their target, while hordes of Squig's are unleashed by their herder's, just as the lunatic Night Goblin wail's around a massive chain-linked Iron ball at their enemies.
