Keep a watchful eye on Aric Wilmunder's site, because he quietly adds to his LEC design document uploads. Unless I'm remembering wrong (entirely possible), I don't think the Forge design document was there originally.
Well, it's not the whole document, but rather the cover only ("at this time"), which nevertheless contains the synopsis for the unproduced game:
Forge is the second game in the Loom trilogy. The game utilizes the 4.0 - 256-color SCUMM system. Forge will retain the same artistic style and story-telling of Loom, incorporating a new user interface appropriate to the new lead character Rusty Nailbender.
The player will assume the role of Rusty Nailbender, the young Blacksmith's apprentice and friend of the weaver, Bobbin Threadbare. Acquiring various ore's from different places, Rusty sets off on a quest to free his Guild from Chaos's control. Rusty's adventures make him aware of his own potential and ability to not only save his Guild but the entire universe of the living.
You might also be surprised to see that the game's project leaders are Kalani Steicher and Mike Ebert (who would go on to work on the likes of Zombies Ate My Neighbors and Indiana Jones' Greatest Adventures) with Brian Moriarty's name nowhere in sight. This is because Moriarty fatefully chose to work on other, ill-fated projects as opposed to a sequel to his game, a decision he's recently indicated he regrets, but how was he to know?
Hopefully the full document gets posted at some point and we can pick over it together, as an exceedingly pathetic team.
