Sorry to bust your bubble b-dog ;-), but even if the
Hall of Judgement original setting was used, the fictitious continent of Etera does not appear to directly translate to the historical viking geography, although it appears much of the mythology would be intact.
I am speculating on this from the limited information gleaned from
the new Kickstarter for Douglas Cole's Dragon Heresy RPG.
P.S. I for one don't mind the creativity encouraged by a fictitious setting but do agree that developed support material is often a benefit.
