hi ,i killed amudusias(spelling) and i have some quests for 4 things to do i think to get into the hall of echos.but i ended up going through the teleporter to ,i believe sentinel island.i am a little lost here.am i supposed to do the 4 quests and go to the hall of echos first,or is it ok to go to sentinel island first?and can i get back to broken valley and/or hall of echos after going to sentinel island?thanks
