I need some help with this bit of terrain. I want to fill the area behind the top of the cliffs with more cliffs, as to acheive the effect that there is a pit below. i have no clue how to do this, and I have read the cliff tutorial.
Note- SEN is being a

with my screenie, so just open up my map and edit it/dtell me what to do. The area that needs editing shows up on the minimap at the top, right of the river.
