Diablo was originally the boy prince, Albrecht.

Killing Albrecht did not destroy Diablo.

Bartuc was originally a member of the Zakarum High Council.

Destroying the corrupted human vessel at the Throne of Destruction did not destroy Bartuc.

The Warlock class reveal trailer has two distinct art styles.

The first, containing the D2R Warlock, is portions of the Act VI epilogue cinematic where the Warlock is subjugated by the demon Bartuc. Like the Diablo 1 epilogue, the hero becomes the villain.

The second style, with the non-Vizjerei mage, is the Diablo IV opening cinematic depicting a Zann Esu clan member completing a ritual to release Bartuc.
