somthing to explore (not a quest)

it would be awesome if there was more to the world to explore i meen there is alout but i have explore most of it even the parts that have nothing in them i have been in and out of pylos hundreads of times most of the time im on i am roaming around tir'an and i have been threw prolix a crazy amount of times, basicly what i am say is i want somthing to explore that isnt a quest i want somthing like a giant cave system to roam around in and it could also have another use sutch as an under ground place for under ground homes also could be used as a library where people can post cool storys and also a place where you can fool around in... i just want somewher to... explore!

already exists... each and every single thing you mentioned.... already exists....so... ur obviously not exploring in the right areas
