Zalgo is to invoke the hive-mind representing chaos.
Invoking the feeling of chaos. With out order. 
The Nezperdian hive-mind of chaos. Zalgo. 
He Waits Behind The Wall, in a palace of tortured glass, served by 
legions forged from the tears of the sleepless dead and clad in armour 
carved from the suffering of mothers. In his left hand he holds a dead 
star, and in his right hand he holds the Candle Whose Light Is Shadow. 
His left hands are stained with the blood of Am Dhaegar. He sings the 
song that ends the earth. The hive-mind that confounds the living, and 
perpetuates the torture of the damned. He takes the eyes, the window 
of the soul, removes the ability to feel...anything but pain. 
Once the eyes have been removed, the soul is removed. The living
husk is testament to cruelty and everlasting soul. He cannot be 
stopped, as fear cannot be stopped. He is inseparable from reality, 
as he exists beyond the veil...waiting. 
Zalgo... He waits behind the thin Wall you have built in your soul 
to free yourself from him... he waits... but he shall come... 
and will sing the song that will end YOU...
