Canto VII (Lines 664-677). The party once again began to adventure to The Elven Dungeon, but were cruelly waylaid by that most notorious of fiends, Be Na Tarth (AKA The Asshole Demon). The initial verses in this canto describe their brief encounter with this horrible creature.

Lo! Appeared one foul and profane!
This creature stood tall and stated:
"Puny beings, all must leave this plane!
"I will destroy you and others!
"This is not the place to be in!
"It is for me and my brothers!"
For this was, The Asshole Demon !!
Kulakoonstru and the rest were
Shocked and appalled that The Asshole,
That most notorious monster,
That vile creature without a soul,
Would maliciously target all.
They tried to teleport away,
The Asshole prevented withdrawal.

It should be noted that the party was saved by the intervention of one of Kulakoonstru’s many powerful friends.
