We could use some details, but it's in NO way necessary to understand the gist of the lore, and if you honestly can't understand "a single sentence" of it then I feel really sorry for you, as it is already extremely dumbed down. Players who are interested in the lore will research it further and those who aren't won't read it even if they had won him a Pulitzer.
Dumbed down as in write it such way that guy without knowledge of FR lore and D&D slang of like drow, plane(which exists officially in D&D since 1st AD&D, and were published in few earlier fan-magazines with some differences) can understand it. You don't need to be sorry for me, since I understand general structure of writte story-line.
Cause I do understand this:
Ellaestia was made by some random guys/gods/fancy race(with magical tittle) from some magical place(if you know more about fantasy - alternate dimension) in some whatever year in whatever epoch,
I don't understand what that epoch was(was it dangerous, peaceful, dominated by something), what was purpose of outsiders, from where they came, and what that year means.
After some years they teleported some inteligent races which lived here.
Okay, pretty straighforward, but those years are written, so they could be important right? Probably not.
And the again some meaningless year in meaningless epoch, there is war beetwen the planes. Okay some kind of world war but between kingdoms and dimensions? Wat? Again everything breaks even more if you are
Then there is this guy Halaster, he kicks some drow ass and if you were interesed in fantasy you know that they are bad elves, with female leadership. He kicks their asses and hauls it out from some place. I have not a single idea why this place and single guy is important. Why drows are important, they had imperium or what? Or were powerful traders or something?
And that's it. I've learned there it was made by some guys, then colonized, then had a war, and more war. Now I do wholly understand a setting/milieu if we want to use Gygaxian slang right? Basics of milieu at least? Nope, not at all. Now do you understand what do I mean by "They wont understand A SINGLE SENTENCE."?
And well some players get discourages by such presentation of lore. I could start caring about it if I would encounter something in it. But such player(who might but don't have to) won't notice, cause he well be scared of by way of presenting lore and required knowledge to understand basics.
Also about details - I did not requested details, I requested accessible information required to get grasp of world and to continue learning about that on my own. Details are lovely when you find them in game. But when you can't get what is the thing behind them in game they are worthless.
EDIT:
Last one thing. If story is supposed to introduce players into game, and most of them wont understand most of it - its badly written. Its badly written because it did not met it requirements called introduce players into setting.
So, i dont good as storywriter, but, i understand this (so, me techie much better than storywriter hehe). And primary - i am have idea and "storyline" but it should be a better writen then it is. Thanks again Gall, that issue added to my TODO list =)
