Diablo Stone

Diablo Stone is available only to people who bought the Collector's Edition of World of Warcraft. Players will receive the item, along with the Zergling Leash and Panda Collar, through the mail when logging on for the first time. It summons Mini Diablo <Lord of Terror>, who will sometimes levitate in the air and breathe fire.

It used to be rewarded from the quest Welcome!

AND THE HEAVENS SHALL TREMBLE, AND MAN SHALL WEEP, AND THE END OF DAYS SHALL--wait, why are you so tall?

• Mini Diablo is inspired by the titular villain of Blizzard's Diablo series of games (the name is literal; it's a very tiny version of the Lord of Terror).
