Should you wish to possess, let's say, a Blood Elf Death Knight on
two separate accounts, each account must be upgraded to our Classic client, then to The Burning Crusade, and then Wrath of the Lich King—individually.
For your specific situation, Kurgath, if you wish to own another account and have it possess the same access as the one on which your level 70 rests, you'll indeed need to purchase another copy of TBC. Don't forgot, though: You'll need to upgrade your trial to a standard account first. You may do this through the provision of an Authentication Key from a boxed copy purchase or via our Direct Online Upgrade feature.
Or, if you don't necessarily want two accounts and, instead, just want to start playing again, feel free to re-subscribe! Heck, you may even want to give our Wrath of the Lich King trial a gander first. :)
