Exit into East Ronfaure and head for H-11 on the map. You will find an area that is made up of half crumbling walls. Look for an arched doorway at H-11 and once you zone thru you will be in King Ramparts Tomb
This area consist of an above ground and a below ground dungeon area - the whole place is considered a dungeon really. There are various level BMs both above and below ground. And for fun the above ground area is a maze. Not a very hard maze, you will figure it out once you have had experience with it.
