At level 15, the portals in Cavendo and Shoushi to the continent to Omishan are open. The terrain of Omishan is significantly less varied than Osteth. It is primarily swampland and rainforest, with a pervasive dark green color. The cities are built in the trees with platforms and bridges. It is an interesting looking architecture, but it is hard to see how they could have been cities. This is the land of the Tumeroks, a lizard like creature that calls the swamps of Omishan home. The monsters and content here are obviously geared towards the middle levels, because of the level limit. There are a few new species, but again, not a whole lot of diversity. In fact, there is somewhat less than on Osteth. The rulers of this land are the Burun, which tend to be tough monsters until around level 30. Again, the landmass is large, but seemingly not too large. The portal systems make it easy to get around. One of the problems that rears its head on Omishan is the issue of 'rubberbanding', or landscape holes. These places cause you to get stuck (and likely killed) in a spot until you can back out of it. Its a bug that continues to annoy me across the continents.
