Since there's been a bit of spam, most of it my own, since my last post...
Quick recap:
Sometime in the mid 21st century, humans abandoned the earth, leaving monkeys to evolve to primacy. When the humans returned, war broke out and the humans seemed to have won. Fortunately, the monkeys, lead by Mr. Chimps, had an ace up their sleve and the crew of the HMS Davey Jones (get it?) trigged the newly-invented (by Cornelius) hypo-temporal drive and went back in time to eradicate the human menace before it could ever threaten monkeydom.
In 4000BC, the monkeys build their first city out of the former spaceship. However, only the original crew has their longevity. New-born "young ones" have a standard simian life-span.
[first temporal event]
The original crew realize that the hypo-temporal drive has ignited, leaving a tear in space-time, through which their young-ones' minds have been implanted knowledge from the ship's library. The crew quickly realizes they've "jumped" to the modern era, as the enemy throws marines, infantry, and god knows what else at them.
During this time, two young privates in the simian infantry, Pvt Bubbles and Pvt Bobo, mysteriously vanish, leaving the capital undefended. In a desperate attempt to secure the city, Cornelius invents the Cross SG Character Flux Generator (which requires precisely one-point-one-"jiga"-watts--heavy) to write a convenient out to this plot-gone-awry. The Cross SG Character Flux Generator activates and General Beast (sans decoration) arrives to flop in the throne room.
Somewhere in that time, a character in a Terry Pratchet novel shows up and founds Christianity

and kidnap our librarian. FARMS!!!
After a bit of (slightly-directed) searching, the deserters are found by another gift of the Cross SG Character Flux Generator, our galleon, the Mysterious Origin. Pvt. Bubbles is tried and convicted of crimes against monkeydom and sentenced to die. Rather than die, however, Pvt. Bubbles accepts special assignment in another Cornelius
plot mover experiment...
The Continuation: Act II, Scene II
INT Cornelius' Lab, 15 years later.
In the middle of the night, Mr. Chimps has been awoken by a frantic call from Cornelius, asking him to rush to his lab immediately
Chimps: This better be important.
Cornelius: Sir, we've done it!
Chimps: You said as much on the telephone. Did what?
Cornelius: Remember that deserter 15 years ago?
Chimps: Babbles? Bibbles? That guy?
Cornelius: Bubbles. Yes sir. Remember the secret project you assigned him to...?
Chimps: Secret assignment...hmm...wait, the cross-gen...WAIT! You...actually...did it?
Cornelius nods with a fiendish smile.
Chimps: You got them to...[chimps makes motions with his hands that only a monkey would understand]...how?
Cornelius: Well, it wasn't difficult, really. Our Private Bubbles was already quite succeptable to the allures of alcohol. And he really hadn't in a long time anyway...
Chimps: You got him drunk? And he...with a human slave?
Cornelius: 38 human slaves, to be precise, Captain. But you probably should meet them.
Cornelius whistles and they hear a door open somewhere off-frame
Chimps: Them?
Cornelius: The colonists, Captain. The future of this planet.
Humanzee.
Dozens of the half-human-half-chimp abominations file into the room. Chimps looks like he'll be sick
Chimps: You made 38 of them?
Cornelius: Oh no sir. 38 was just the original stock you see before you. If you count the clones, we have thousands.
CHimps: Thousands? What the hell are we gonna do with them all?
Cornelius: They're colonists sir.
Chimps: You want to make a city out of them?
Cornelius: Well, more like a top-secret research facility. The civilian population probably isn't ready for Humanzee, yet.
Chimps: I agree. This can't get out, Cornelius. It'll ruin us. Worse, if the humans find out, they'll all unite under one banner and crushe us. You sure these...things...are worth it?
Cornelius: Positive, Captain. Humanzee holds the key to mutual cohabitation of ape and man on this planet. Without it, the killing will never cease.
To be continued...
