Easy solution:

Use the title "Vestige" when in discussion as it's alot easier. But add an addendum like:

"The vestige, also known as The Soulless One was a hero in the second era blah blah blah"

Officially, you could refer the hero either way. However remember that "Vestige" is the title given by the Prophet. You earn dozens more titles along the way like "Hand of Almalexia" and "Hero of Davons Watch" if your in the Ebonhart Pact.

So The Soulless one is probably more accurate, but Vestige is more popular and far easier in general conversation.
