Which BM Resources did you first start out with?

I, too, started off the the elusive "Kingdom that existed before the Great Rain of Fire" references in the later Mystara material. Most of my exposure came from having heard of the DA series, and what little there was in the Hollow World and Wrath of the Immortals boxed sets.

It was only when I got all growed up that I had the money to pony up for a copy of DA1 off E-bay (quasi birthday present one year from the missus).

In working my way though Thorn's Chronicle, I'm basing huge chunks of the history off of what I gleaned from DA 1.
