Spoiler alert! Don't read if you haven't completed the original Diablo from 1996.

----

At the end of the original Diablo, the hero shoves Diablo's soulstone into his or her forehead. That ending is identical for any hero choice.

Is there a canonical "which hero it was" fact in Diablo II? e.g. do we know that it was a warrior that used the soulstone, and subsequently became the host for Diablo's new form?
