[Vallanor]

As an unguilded paladin who doesn't usually have time to commit to a several hours long raid (and who probably wouldn't be needed anyway), I was wondering if it is logistically possible to buy looting rights to some pally drops in Sky? I've never been to the zone so I don't really understand how the islands work, but if I was looking for something from Bazzt Zzzt would I be physically able to head up there and grab it if it dropped? Or do you kinda need to be along for the raid for that to work out? If that is possible, how would it work?
