Yes Welly, we have played the game. We are also just as big a fans of it as you are, and know the history of it backwards and fowards as you do, BUT, that story was not intended to be an alternative to the Myth 2 ending for Mything purposes, but an alternative ending to Myth 2 for my Guild's purposes.
Myth is dying, I was there the night Bungie.net died. :*( When I wrote that story I used some poetic liscense to fit that story to my Guilds' needs. I wanted specifically to deal with our beloved server dying, and our forced move to find other alternatives and games.
The story written on www.thefallenlords.com was specifically written for my Guild's move from Mything to other games, specifically ShadowBane. We wanted a story which showed off the rich history built and maintained in the Myth stories. But, we also wanted a story that would be somewhat plausible in explaining our move to ShadowBane.
My guild is composed entirely of Mythers, most of whom, have played both M1, M2 and M3. Most were there the day the server died. Most have been Mything friends for years. And most loved the story, because it gave them the Myth identity that they wanted. And that was all that mattered to me when I wrote the story.
ps. Some of the text was copied directly from the Myth 2. Huzahhh to Bungie for being such creative writers in the first place.
