Just wanted to say howdy! I am brand new to RS because a friend told me about it (only logged on twice)

. RSBNB has been the best resource I've seen to get myself acclimated to this MMORPG.
I do have a newbie question though...I was walking from Lumbridge to the bank in Draynor and got ganked

. I tried to heal by eating some of the cooked beef I had but I still died shortly. Are there monsters in that area that will hostile you without you attacking first (the goblins seem to wait until yiou strike first)? And just to be clear, PKing is only allowed in the Wildy right? No one can come up and kill me in towns (even on PKing servers)?
Thanks lots and sorry for asking obvious questions.
