Beach Fort
From Drunkapedia
An outpost located on the western shore of Northern Osteth. Take the Lady Maila Estates portal in Mayoi at 60.8S 80.3E then run NW to 76.0N 49.1W. If you are going to be turning in a lot of chorizite you can tie to The Pit near stonehold. Near the entrance is a hole that drops all the way to the bottom, where there's a portal to Beach Fort (the portal is untiable but it takes 10sec to jump down and use portal).
