The Platinum Discs

This object is an incredible find. The ancient Titans, or the Creators as these discs refer to them as, are the link to our enchanted creation, if the lore stored in here is correct! We'll need to invest as much research time into this as possible.

As for you, heroic <class>, take this voucher to Dinita Stonemantle at the vault. It grants you what I think is a fitting for such a tremendous find!

Return to me directly when you are ready; there is much more to do for the Explorers' League!

Welcome to the Vault of Ironforge, <name>. What may I do for you today?

As yes, a voucher from the Explorers' League... and quite the valuable one, might I add.

The Explorers' League lends me the authority to offer you a choice in your compensation directly from their vault. You are to receive this item, and you may choose between five superior healing potions or five greater mana potions as your reward.
