Vahtos' Apprentice's - found in multiple places throughout three zones. This series rewards five pieces of non-bound Superior-quality jewelry. Obviously, you are not going to complete this series in Silverspring. See the links, below, to find all the pieces!
All the Vahtos' Apprentice items do NOT become Bound and, when you outgrow it, you can give it to a younger friend or one of your alts. Even if every character on your account does not finish every one of these quests, you can eventually accumulate a complete set of Physical (Vahtos' Strike) and Magical (Vahtos' Spell) accessories for your new characters.
