Lalafell and Dwarves... Plot Hole Potential?

[RenewalXVII]

The Warriors of Darkness came to the Source via an Ascian method: they killed their physical bodies, and transcended worlds via their souls alone, inhabiting new bodies on the Source. The Devout of Darkness may not have even been a Dwarf on the Source for all we know.

I'm pretty sure that this method and its incongruities with our character (i.e., there's no sensible way we're physically killing off our body to get a new one) was brought up at the Fanfest or an interview at the same time, and it was mentioned we would be traveling to the First via a different method, that would preserve us body and soul.
