The Eight-Pointed Star is one of those levels of the City Underground that can be quite peaceful or quite dangerous, depending upon whom you encounter. The dominant force within this level is a druidic circle, so it's probably not a great idea to do anything too ecologically damaging.
Perhaps the greatest attraction on this level is the Embryonic Zoo, which contains halls upon halls of embryonic animals and beast preserved within special, magically enchanted glass jars. Apparently the embryos are still, technically, alive, as long as they remain within their jars. Note that this attraction probably isn't for those of a sensitive or gentle disposition.
