Pah! I am no mere gremlin. I am the thousand eyes that watch you in the darkness. I am the hissing blade that whispers your doom. Tear down every wall and cog in this accursed place and you will find only shadows.
I cannot be stopped by the likes of you! Hsst!
We'll see about that.
Herex
You cannot stop what you cannot see.
