Well, you can get into Arakand garden by throwing 1 teleporter stone outside Verdistis gates, make sure you don't drop and use them, you will need them to get into Arakand, now, head northwest all the way, somewhere around the northwest corner will be Arakand garden! Go to the area sealed by a short stone wall, throw a teleporter stone over there and THEN drop and use the pyramid, if you do complete this quest, then there is a small chance that the imp will appear at the council chamber when you scy for him at the council, if not, try the broken imp council member fix (sorry I don't have the link for it)
