The Arch is huge, like the front face of a castle, but with a giant keyhole 
archway bored right through the middle. The huge keyhole opening blazes with 
blue electric. A pair of enormous, shiny chrome trolls with massive war axes 
stand guard in front of the keyhole. An army of paranormal animals flank the 
trolls: aardwolves and bogies, boobrie birds, deathrattlers and devil jack 
diamonds, firedrakes, gila demons, greater wolverines. Hell hounds and more. The 
ledges above the keyhole are lined with harpies and troglodytes, black annis 
apes like huge orangutans with vicious fangs. Up on the battlements squats a 
wyvern.
