On Kefen A, the natives are quite sure of one thing. The Universe and Kefen always were, always are, and always will be. Notions of worlds getting shattered are for morons. Catastrophes with unique or genuinely world-changing dimensions do not happen.
The natives are short, a bit pudgy, green-skinned with a cooling fin of darker green rising a foot above the head which rests at four foot tall. They have no incisor or canine type teeth; instead they only have molars which works as they are vegetarians.
Kefenites have very little genetic diversity which necessitates the approval of the Genetic Board before anyone can be married. Some kooks regard this as proof that at some distant point in the past, most Kefenites were wiped out, and a very few bloodlines repopulated the planet. These whackos also point out the deep damage from canyons, the circular gulfs, the volcanoes, and the massive amounts of extinct animal fossils all layed out as if they had been swept up by massive amounts of water, and then the water had slowed as it hit a sandbar or a mountain range.
But there are very few of these kooks.
Unfortunately, there is an ancient prophecy that the Angel of the Last Days shall appear amidst corn, and he shall stand tall above mortal men with a skin like (pale as death, dark like the night, or yellow like the last sunrise which he heralds). In other words, there is a prophecy that when the verser arrives in a cornfield that things are about to get Really Bad.
These 'kooks' (and some of them are) will try to meet the person there will be strange rumours about (because the verser looks so obviously alien).
Later, there will be another problem...a comet is headed inwar. With hapless fearlessness, the locals prepare for a comet-watching party.
But, they're about to get a closer look than they want. The only thing that can save them is the partially built Kook spacship, and a stolen nuclear warhead.
And this is a Uniformatarian theory world about to receive an educaton in Catastrohphism.
Unfortunately, there is an ancient prophecy that the Angel of the Last Days shall appear amidst corn, and he shall stand tall above mortal men with a skin like (pale as death, dark like the night, or yellow like the last sunrise which he heralds).
Or red like the nuclear fire which will follow his arrival.
Thank you, John.
On Kefen B, the natives have a similar viewpoint, and its correct. The comet will pass at a safe distance, and anyone so foolish as to steal a nuclear bomb to lauch aboard a rickety spaceship is going to be in Heap Big Trouble when they land.
There is a prophecy similar to the other one which includes the red like nuclear fire, OR one of the others (depending on what the player looks like-its a GM trick since GM's aren't actually omniscient but we play such on TV). However, the Prophet Alistarchus has a reputation for vague, and abundant, and occasionally totally wrong prophecies. In fact, he was a very smart madman with a good ability to see future patterns due to intuition, but he was not a prophet.
It will see that the comet will come really close, but the Kefenites in general, will not worry. One reason for the closeness predicted is a misplaced decimal point buried deeply in the calculation. It would take a week of study, and high-level math skills to uncover the error. Actually the comet will not come nearly as close as predicted.
One other difference is very early history. When the Kefenites rebelled against their maker, the Awe, he cursed them and the ground, but not as harshly as Jehovah cursed Adam and the Earth. Thus, the solar system of this world really does run like a perfectly smooth system.
As to the similarity of Kefenite DNA, the reason has more to do with the Time of Ancient Wars in Kefen B when for several hundred years war, and its attendant problems swept the whole planet several thousand years ago. This followed the first discovery and usage of narcotics and hallucinogens. Since then, the Kefenites have become extremely paranoid about placing any chemicals in their bodies.
No problem Eric. I could see where you were going with that, so I figured I would lend a hand.
