A huge monument dominates the center of this donut-shaped confluence of avenues. Several dwarven warriors, rendered in gleaming white marble, battle a dozen orcs, depicted in black obsidian. Several stone benches rest around the monument, facing outward in a circular pattern, while other benches sit on the outer edges of the circle, facing the monument. Wide streets lead in from the north, south, east and west, and each thoroughfare is lined with luminescent toadstools in wide stone pots. You also see an octagonal stone receptacle and a granite slab.
Obvious exits: north, east, south, west

Hm. See whatcha got there is your whooflots are all gebartniked up. You just need to yillawhack your muntnors a couple of times and you're good to go.

And if that doesn't work, try disabling lich (launch lich.rbw as an administrator and click on the Install tab, then click on the Uninstall (or possibly disable, something like that)) and logging in through the website. Once you get all the way logged in, quit out, then log in again using lich (re-install it, or go through lich's game entry). When I've had the same issue, that's fixed it.
