Sky Terror
Hellspawn
There are more than one of these kinds of demons.
These demons, weightless and formless, living in the sky and sometimes low to the ground, consist of acid, various winds, and a booming electrical cry.
They are called Sky Terror regardless of individuality.
In particular, there are 2 demons worth mentioning here:
Sky Terror 1.
Sky Terror is the 'weather' that resides above Phayne's castle. It is a constant and tremendous force, creating tornadoes and corrosive rain, and a loud roar strong enough to deafen/burst the ears of those underneath it. Lightning will shoot down, following any living thing that moves in its sight. (you could potentially avoid getting electrocuted if you stood perfectly still, but the acid rain that beats down on you will force you to move eventually, or else you'll be corroded to death. The harsh winds will also knock you around into things, which could impale you into rocks or other sharp objects flying around. You're bound to get stuck/wedged somewhere and corroded to death anyway.
This demon is stationary, dwelling in one spot all the time. It is uncertain if Phayne has bound it above his castle, to deter visitors (not that anyone would want to visit him anyway) or if it has simply decided to stay there of its own freewill. (Though it is debated whether this demon has a brain intelligent enough for any thoughts at all.)
Many that have encountered this demon have desperately searched for shelter from its destructive, harmful nature. Those that choose to enter Phayne's castle, (unknowingly or in a frenzied attempt to find shelter) face the terrors that lie within. The castle will close shut behind them and they are lost to the endless, dark hallways forever.
Those that enter Phayne's castle eventually become Crawlers. Mindless, mad demons, half broken individuals that crawl the halls of the Fire Lord's enchanted castle, still searching for the way out... or their next meal. They will eventually break from the strain and madness, becoming part of the castle itself in time.
Sky Terror 2.
This demon has a name, though no one knows it. It has a brain too, and while its a fairly primitive brain, it uses it to chase down land walkers for fun.
Much like its other 'siblings', it consists of acidic rain, harsh winds and an electrical booming voice. The only difference is that this one is smart enough to use its abilities tactfully, and not all at once, should it choose.
One moment you'll be walking under clear skies when BAM, suddenly you're surrounded by a terrifying storm, unable to find shelter or escape from its wrath, as the storm above will follow you wherever you go. It has the patience to wait for you, should you actually find the safety of a shelter. Eventually you'll try to leave and it will still be there (it IS possible to outsmart it though). Those unfortunate enough to be caught under this Sky Terror end up being Broken (killed). Their lifeless forms will either be left where they die to be found by others, fused into the ground/environment, or will be devoured by the Sky Terror itself.
