A Members object was the name given to any item that could only be used on a Pay-to-play world, when logged into a Free-to-play world. It could not be traded nor equipped. If it was already equipped, the player would still have it equipped on the free world but it couldn't be put back on until they switched to a members world. Member objects lost their bonuses and item commands (if it had any). All member objects had the same examine text: "You need to be a member to use this object".
Member objects could not be sold, traded or drop traded, if the latter was done they would just end up disappearing after being a long time in the ground.
A pure f2p player could get a members object if he or she entered Elvarg's lair soon after another player had defeated Elvarg. Having a members object on a free-to-play world, however, was of no use.
