That was indeed Ygerna, not Talana that gave you the gift - Dragon. No idea what`s up with Talana, i`m just guessing she`s still alive somewhere, it isnt proven that she`s dead since Lord Arbens ghost was haunting in the church cellars. If Talana would be long dead, then you wouldn`t have met Arbens ghost in the first place. You ended up traped in the Hall of Echoes together with Lucian, the Divine, who still is alive in fact.
