Of the plot, I think.
I think one character could do this, but i'll confirm and you don't need Teleport, but you will need yarrow.
You need a rogue and a lizard (or shovel) and good wits. Also a lock pick.
Near migo (give him the yarrow to stop him turning you into marmalade) there is a hidden entrance to the fire slug cave. They remain neutral until you annoy the Queen. She can be avoided by a vine ladder. This takes you into the cells. The door facing needs a pick and takes you into the main fort and the silent monks who don't react (well not to my party anyway).
Go past the dogs cages (you can go in if you spoke to Buddy and give the right responses) and you can loot most of the Flensers room if you leave the middle out. On the left hand side (if you entered at the bottom) the sewer leads out of the fort. (I didn't meet a maniac, either a bug or something I did earlier? )
There is a statue in the swamp that keys you fast travel back if you want to (in classic difficulty).
That's the simplest way without teleportation, I think. I hope I remembered it right. It was last night and I have old brain.
