Love 'em or loath 'em, the Kzinti have been a semi-part of the Trek universe since Larry Niven adapted The Soft Weapon for the Animated Series. Now I kind of like the Kzinti, and I like the way Starcharts kind of hinted at them, and I also liked the idea that the Tzenkethi were intended to be the Kzinti.
So anyway, I've been working on adapting the Kzinti for use in my campaign. So far, I've mainly just done the basics of some of the chronology. So this is still a work in progress, but I thought a few folks might be interested. Comments are, as always, welcome.
OK, I've done a bit of work on a possible Kzinti timeline. There's some more stuff I want to put in here, and obviously I want to extend it beyond 2276. But this is a decent start.
c 1300 AD
The race known only as the Hur’q invade the Kzin homeworld. However, they find the Kzinti more formidable than the Klingon Empire, and quickly write off the planet as a lost cause. The Kzinti force captured Hur’q scientists to genetically alter the Kzin species, making the males idealised Alphas, and the females subsentient slaves. The captured Hur’q do not survive for long, though they leave behind numerous technologicical items, which several Kzinti warlords use to attack their neighbours.
1402 AD
After repeated failed attempts to understand captured Hur’q technology, the last Hur’q device finally fails, and the warlord Ch’Rarn orders the now useless devices sealed away in a secure location for future study.
1417 AD
The warlord Ch’Rarn dies in battle. With his death, the location of the cached Hur'q technology is lost, and it's existence soon fades into legend.
2123
The ECS Fortune disappears while on a cargo run from Earth to Rigel.
2125
The Earth vessel Valiant discovers the drifting hulk of the ECS Fortune. A survey team dicsovers the gnawed bones of the vessel's captain, but no trace is ever found of the rest of the crew.
2130
All contact is lost with the Starfleet vessel Gallant, while investigating the disappearance of several Earth cargo ships.
2131
Starfleet vessel Intrepid discovers the shattered remains of the Gallant in deep space. An investigation reveals a picthed battle had been fought aboard the Gallant, and the skeletal remains of many of the crew are scattered throughout the ship. Autopsies show evidence that the bones had been chewed on, suggesting that the crew may have been eaten.
Following the trail left by the Gallant's logs, the Intrepid continues the Gallant's investigations
2132
Due in large part to the work of the lost crew of the Gallant, the Intrepid locates the unidentified vessel (in later years, it would become clear that the vessel was Kzinti in origin) responsible for the attack on the Gallant. After a fierce battle, the hostile ship is destroyed, with no survivors, though the Intrepid does succeed in recovering some partial remains of the vessel's crew.
2140
The Kzinti begin making raids along the Klingon border.
2145
Kzin scouts probe the Kannaga system, as the first stage of an invasion.
c 2150
Kzinti warriors attack the Klingon colony of Kannaga. After a fierce battle the Klingons prevail, but at a high cost in both personnel and resources. The damage to the colony will take years to recover. The Kzinti invaders are completely wiped out.
c 2150
In retaliation for the attack on Kannaga, the Klingons send a dozen ships out to locate and scout out Kzinti worlds. None will ever return.
2163
Kzin scouts quietly probe the Alpha Centauri System, looking for weakness.
2166
U.S.S. Archon comes under attack by a Kzin Warship while surveying the Gamma Trianguli system. The Archon is victorious.
2167
The Kzinti attempt to invade Alpha Centauri, but are soundly defeated by the Federation Starfleet.
2168
Enraged by suffering a second defeat in recent years, the Kzinti set their sights on obliterating the Federation. They begin making plans to attack Earth.
2169
The largest assault fleet in Kzinti spacefaring history enters Sector 001. They are soundly defeated by the Federation Starfleet before even entering the Sol system, due largely to superior Federation technology. The survivors limp back to Kzin on emergency power.
2188
After more than a decade of rebuilding, the furious Kzinti launch a second assault against the Federation, attacking both Earth and Vulcan in a daring two-pronged assault. Though the Federation takes heavier casualties this time, the Kzinti are again defeated, with more than a quarter of their fleet destroyed. Less than half the Kzinti fleet make it back to the homeworld, due to an opportunistic attack while en route, by the grudge-holding Klingons.
2195
Under the inspired leadership of Chsst-Admiral, a third Kzinti assault is launched against Earth. Despite the superior Federation technology, Chsst Admiral’s more subtle tactics result in the Federation taking heavy casualties, and much of the Mars Defense Perimeter destroyed before reinforcements are able to drive back the attackers. The Daedalus class USS Intrepid, under Captain Samir Ahmed, is destroyed during the battle.
2200
A fourth assault on the Federation is commanded by the wily, Chuut-Riit. The Kzinti dispatches smaller fleets to attack both Andor and Vulcan, in an attempt to distract attention from Earth. The ploy almost succeeds, but with both sides taking heavy casualties, though the Federation prevails.
2201
Tired of the continual Kzinti attacks, the Federation takes the war to the Kzinti. Despite the objections of the Vulcans, a Federation fleet enters Kzinti space to end the Kzinti threat for once and for all.
2202
Following a decisive confrontation, Kzin falls to the Federation. The disgraced Chuut-Riit is eaten by his family.
2203
With little choice, the Kzinti are forced to sign the Treaty of Sirius, denying them the use of advanced weaponry, and limiting their spacefaring capabilities to police vessels only. As part of the treaty, a Federation presence is established on Kzin to monitor compliance. Despite this, skirmishes with ‘rogue’ vessels will continue for many years.
2205
The Kzinti begin planning a fifth assault on the Federation, one that will take many years to come to fruition.
2217
A small group of Kzinti begin calling for reform, arguing that the Kzin must change with the times or be wiped out.
2218
The Reformation movement begins to gain momentum, despite the best efforts of the power-holding traditionalists to destroy it.
2239
The Kzinti patriarch dies, his replacement orders the military to begin rounding up and executing all reformists, forcing the reformation movement underground, and inadvertently rallying popular support to what is now a full-fledged rebellion. The Federation attempts to mediate the dispute, but to no avail.
As a result of the internal disputes fracturing Kzin society, the Patriarch is forced to sideline plans for a fifth assault on the Federation.
2260
Despite fighting a guerrilla war, the Reformation movement continues to garner support on Kzin, despite the Patriarch’s best efforts to wipe them out. Kzinti society is polarised on the issue, with many still supporting traditional values, while others take up the banner of reformation, creating a cultural rift that may destroy Kzinti society once and for all.
2269 (stardate 4187.3)
Archaeologists working on Kzin discover a Slaver stasis box. Under the terms of the Treaty of Sirius, the Kzinti are forced to surrender the box to Federation authorities. Enterprise crewmembers Commander Spock, and Lieutenants Sulu and Uhura are assigned to transport the box to Starbase 25 aboard the shuttlecraft Copernicus. While en route, the Copernicus crew are lured into investigating the possibility of another stasis box in the vicinity of Beta Lyrae. This later turns out to be a trap sprung by supposedly rogue Kzinti, who capture the box and the Enterprise crewmembers. Upon opening, the box proves to contain what seems to be a weapon, but it is destroyed when the Kzinti Chuft-Commander inadvertently activates a self-destruct, leaving both him and his crew dead.
2271
In an attempt to generate inter-species understanding, the Kzinti Officer Teela-Commander is assigned to the USS Lexington as part of a cultural exchange program.
2275
The Kzinti Reformation movement succeeds in overthrowing the Patriarch. Instead of eating the Patriarch and his supporters, the new Patriarch orders them exiled from Kzinti space. Despite being spared by his opponents, the disgraced former Patriarch is eaten by his family.
2276
Swearing vengeance against the traitors of the Kzinti Hegemony, the exiled Kzinti traditionalists settle on the planet Tzenketh.
