Ok, as my name is Moar_TNG my episodes will be placed in this timeframe for the most part.
Now, as an outside observer who has seen The Whole Picture, I know for a fact that the Borg were "known of" in Archer's time, they may or may not have been known in TOS/Movie times depending on what the El-Aurians refugees that the E-B picked up might have mentioned... They may have been known pre-TNG (depends on when the Raven left) and after that well then it gets ugly.
Going to start this story around the time of Encounter At Farpoint, and two of the players are going to play characters on assignment from Starfleet Security/Starfleet Tactical looking for evidence of the "Bio Mechanical Race." They aren't taken seriously for awhile, up until the Enterprise-D encounters the destruction along the RNZ... then things kick into high gear after the encounter at J-25...
I want to "end" this story arc at the Battle Of Wolf 359. I'm thinking about putting the players on an old refit 3-engine Dreadnought that has been in service from Kirk's time but has been refitted along the way.... currently it is slated for retirement at the end of the decade to be replaced by a new-build Akira class ship.
Couple of questions before I start hammering this out: is there any on-screen evidence for the wreckage of a three nacelle ship in the Graveyard scene? I seem to recall there was. If so, then our ship gets destroyed. If not then the ship manages to survive somehow but at extreme personal cost.
Second, Minos. I'm going to tie that to the Borg. The Minosians managed to get ahold of some Borg tech and it wiped them out utterly (Echo-Papa drones anyone?) Aside from the one canned adventure anyone do anything with Minos, canon, novel, game?
Third: well I'm distracted at the moment doing some CAD work and I forgot the third thing.
Anyway thanks for your comments/insight.
