Its an open ended area. There are multiple places to go, but that area just serves as the connecting point to them. The enemies have a line of sight and if you keep running far enough they will leave you aloneI found some awesome leather pants for my female character in the Lower Undead Burg and I have been wearing them ever since then. I have much more defensive and badass leg pieces but I'm never going to wear them because the idea of this chick running around the world of Dark Souls in leather pants slaying everything in her path is just too good.
Anyway I found my way to an area in Darkroot Garden that hasthat can literally three-shot me. I tried going back a few times and I can kill one or two of them but I always die eventually. I'm guessing this area is way too high level for me and I should go somewhere else?near-invisible enemies
