Someone else wrote the lore, I can't remember the name, so there is a lot more. Where it can be found if anywhere I don't know, I never read any of it for this mod even
. Even Tolkien's fantasy is too much fantasy for me sometimes so this is over the top for me. Squeaks definitely got it from elsewhere though which is the main reason no one else has permission to release a campaign with all this lore in it (at least not on this site due to TOS).
Edit; This mod was originally titled Dragonborn (changed because of Skyrim) so searching for that may be better than searching for Dragondawn.
