Throughout the ages, ships have always had their hitchhikers of some kind or another in the form of animals that find their way onboard either in or in pursuit of the food brought on as cargo. On Earth, rats have always been the most common, so common that they that even ended up on colony worlds tagging along in starships. Some new alien species, similar in habit to terrestrial rats have also become regular travelers on starships as they are brought aboard with the cargo, or manage to sneak inside the ship when the doors are left open. Regardless of the exact species, the generic and traditional term for such stowaways among crews is ‘rats”.

Crews of ships transiting jumpspace have reported a lot of strange and sometimes eerie encounters inside their ships during that long week in jump. The vast majority of these is attributable to the inevitable combination of boredom, drink, and drugs used to make the trip less tedious, or just from a session of staring into the Mandelbrot patterned gray swirling of raw jumpspace itself. A very small number of sightings are corroborated by video and data recordings, and have been so consistent across the wide spectrum of ship crews that they are most certainly real encounters with something odd. Jump rats, however, are the one encounter that not only leases video and witnesses, but also leaves physical evidence.

Jump rats are lifeforms unique to jumpspace and while they cannot physically exist or live for long in realspace, they can enter for extended times the realspace bubble that exists in starships while those ships are transiting jumpspace. Jump rats present on a ship that drops out of jumpspace will vanish, lending some credit to the theory that though the animals manifest physically on a ship they are still linked somehow to jumpspace. Some believe they may only be the tips of some entity protruding into a ship’s realspace environment while the majority of the larger creature remains in jumpspace. Regardless of the true nature of jump rats, it is clear that they can only manifest while the ship is in jumpspace, and not appear in ships travelling realspace.

Jump rats manifest as a small, slightly luminescent blue-green animal. They are egg-shaped with a long, slightly flattened tail on the round end, and a mass of cilia-like feelers along the ventral surface that are used for locomotion. Two bright red and beady eyes are on the top of the pointed end of the body, which then terminates in a rasp-filled maw. The animal is extremely fast. When startled or frightened the jump rat can ‘phase’ through solid objects to escape. They tend to prefer darkness, but this may only be due to their timid nature since no one understands how they ‘see’, or what senses they have. People have approached them closely enough to almost touch a jump rat, only to have it suddenly ‘drop’ through the floor or wall to reappear on the other side darting away.

Jump rats appear to be solitary in that no social behavior has ever been observed among them, but when they infest a ship in jumpspace they usually appear scattered throughout in numbers ranging from 1-12 rats. Once inside the ship they will usually stay, with the numbers of jump rats fluctuating, perhaps with individuals phasing out and new ones in for the duration of the jump. When the ship drops out of jump, the rats vanish. Jump rats are not affected by toxins or tranquilizing gases, nor does vacuum appear to bother them. Since they can phase through walls traps cannot hold them. The only way to eliminate the animals is to hunt them down and hit them with a laser. Any other kind of weapon has no effect on the animal since its startle reflex is fast enough that the jump rat will simply drop through a floor or whatever object it is on before the weapon (or the weapon’s projectile) can hit the beast. There have been hilarious videos circulated showing frustrated and angry crew members shooting up desks, coffee-makers, and ATV tires when they fire grenades or automatic weapons ate darting jump rats with the inevitable destruction to property …and a jump rat darting out of the smoke to safety. Often, with the video slowed enough, you can actually see the jump rat appear to drop right through the computer station it was feeding on milliseconds before the slugs from a weapon obliterate the device while the rat scampers away. The only weapon 100% effective against the jump rat is the laser.

Jump rats feed on energy sources and polymer compounds. It may just be that they just appear to feed on the polymer materials but are only chewing through them to get closer to the energy source, but it is hard to tell. Crews have had furniture chewed up, tabletops, clothing, armor, vacc suits, carpets, and even the tires on ATV’s shredded by the animals. It appears nearly anything with polymers in their makeup is fair game to the jump rat. Jump rats may be looking for energy sources, or perhaps they enjoy the taste of plastics, but no matter what the reason it can be destructive and sometimes dangerous. A single jump rat will destroy and/or consume up to 1kg of material in just a few minutes. If it gains access to and energy source, a jump rat will consume an average of 200kw/sec for as long as the rat is attached to the source, or until the source is drained. Batteries, cables, power couplings, generators, and even a ship’s power plant are all sources that attract the animals. Though the jump rat drains the energy through induction and need not actually come in direct contact with the energy, it will reduce the shielding or insulation around the energy source to get as close as possible to the source. This explains the gnawed shielding on fusion bottles and exposed power feeds with piles of shredded insulation left below them.

Obviously, this feeding behavior is the hazard jump rats present. There have been no reports of any attacks on passengers or crew by the animals. The danger and nuisance lies in finding one’s vacc suit gaskets chewed to shreds, or the drilling laser power packs drained, or worse yet, the power plant shielding full of holes left by burrowing jump rats. Crews in jumpspace need to be alert in their rounds to ensure any manifestation of jump rats is eliminated immediately and thoroughly to avoid potentially catastrophic results.
 
"At j-CON® we have made The Better Mousetrap!®

Using the finest materials for a tightly-woven and reinforced Faraday cage with a snap lid we have created the first, functional Jump rat trap. The little pests are lured into the cage by a handful of leaky batteries and when the jump rat starts chewing the door slams shut and ...ZAP! The laser inside clears the trap while leaving the bait intact and no mess!

The next time you enter jump make sure you take a few Better Mousetraps® with you to scatter around the power plant and jump coils - you'll jump with confidence knowing that no rats are going to be chewing on your conduits!!"
 
Awww, no jump cats?

:D

Then we'd have to have jump dogs, too, to chase the cats as they chase the rats. We have vargr, so maybe they count.

Alternately experiments with tiny quantum-phasing modulators for the cats to wear so they can chase the jump rats through walls. Along with a laser turret on its little helmet to zap the jump rat with. Yes! Bwah-ha-ha!

And they think me mad!

the drow (blue darrians) hunted the jump dogs to extinction pre-maghiz....

And, then a jump cow to toss the dog. Then a maiden to milk the cow. Then a man... then a priest, then a rooster............

Pretty soon you have a full ship and not a dang one is a paying passenger!

Wait a minute... a "jump maiden"? Hmmmmm... that could be interesting.................
 
A few suggestions:

Fiber optics or other similar wiring where possible.
All cabling in conduit or with heavy braided metal jacket shielding...
 
There was a short story in Analog SF magazine a long time ago, in the John Campbell era, about a starship in what would be regarded as hyperspace conducting an experiment, and suddenly being intercepted by a much larger ship and loaded with a wide range of cargo. The cargo did not vanish when the ship returned to normal space.

In James Schmitz's Witches of Karres has an interdimensional creature, the Vatch, that can become present on a starship while in space, and has the potential of putting things on board.

Either would be an interesting idea in this line.
 
What I have generally found lacking in Traveller were a lot of ideas for adventures while in jump. Pretty much everyone uses it as a chance to catch up on player questions and book keeping, and maybe once in a while runs something like a hijacking attempt or some Voyage of the Space Beagle-type monster, but I've always add some more things for the players to do on a routine basis.

A periodic check for jump rats would fit the bill since the one time the players forgot to check would be when the little buggers showed up.
 
If you can, check out "Star Death" by EC Tubb, it is all about crazy adventures in jump space.
 
I'm halfway book 6 in his Dumarest series. I started it because everyone keeps telling me how it was where a lot of the ideas for Traveller came form. I can see that now, and they are pretty good, quick reads. Since for the most part i like the series I'll have to see if I can find "Star Death".
 
Tubb is pulpy, but decent enough if you like sci-fi (which I do). My free time away from work and school, which is none lately; is reading old books, I found a bookstore with an ancient basement filled with used sci-fi to that extent.
 
Had an alien in a lanthanum suit appear onboard a ship passing through an empty hex far off the normal routes. He hailed from a xenophobic race who were denizens of pocket universe hidden in jump space and were curious about the intruders into their N-space shadow, wanting to know what they knew. He basically ignored the crew initially as he made his way to the computer room. The crew managed to knock him out when the resident psionic convinced him to take a nap. They fiddled with his suit and the ship dropped into the alien realm. They managed to hold off boarders for several hours with a mix of psionics and fire power until ammo ran short and the aliens broke through their makeshift barricades. Fortunately, there were no serious injuries on either side as the players fired mostly warning shots before surrendering and they didn't kill the intruder. The xenophobes took them prisoner, interrogated them for a while with same scary looking devices, allowed them a short demonstration of TL15+ goodies, then packed them back in their ship and had the intruder return them to N-space far away from the empty hex. After a little exposition, the intruder turned a dial on his suit and phased out.

This wouldn't be the last time they had contact with the intruder; he failed the clear the computer of some navigation and sensor data that allowed the players to find the pocket universe a second time. But that's a different story.

Hey, wadda ya want? ;) I'm a product of the TV I watch. I actually got the core idea of a guy in a metal suit from the 80's cartoon Silverhawks. You're right about Star Trek trying to corner the market on sci fi stories though, tough to have an original thought without somehow plagiarizing something from one of the Trek series. We've become saturated by Trek.

I'm thinking of using this adventure again but this time enlisting the players to bring the aliens info on the source of their xenophobia, an ancient enemy who doesn't know of the pocket universe or that their rivals still exist. Of course the players will find themselves caught up in something well beyond their capability to handle.
