soo yeah posted that in exploit a week ago. ( i did not know this forum existed.)
Asked it to be moved here . But instead it simply got closed because it was judged useless.( i assume its not possible to move it)
Soo its just a fun quest item that spawn ligthwell and that can be used anywhere. Serve no purpose other than making trail of ligthwell.
Theres a quest in Eastern Plagueland -http://www.wowhead.com/quest=27530
that give you an argent Ligthwell and with it you can put ligthweel anywhere.
thats it .
Have fun =).
