After you have knocked of the 2 trolls attacking Ferris and Jarvis you come across Homer?? from there go south east and you will see some tufts of straw in the lower east corner of one of an enclosed area. Move the tufts or bundles of straw to see the teleporter.

DD Rocks!!

God grant me the serenity to accept the things I cannot change, courage to change the things I can and the wisdom to hide the bodies of those I had to kill, because they pissed me off.
