Even more interesting to me, from a game history perspective, is the Time-Locked Box and its occupant, the Bronze Whelpling. This is a pet with, as one might expect, a long history within World of Warcraft.
Fun fact: the bronze whelpling and its summon spell were created in 2004, but never made it into the game.- Jonathan LeCraft (@TheCrafticus) August 11, 2014
That's a long time to wait for a pet to be introduced. But at last it's here, right? Looking forward to both, at least from the perspective of a guy who wants people to be happy.
