What gives you the sense that human beings are constantly making incursions into these races' territory and killing them on an enormous scale?
Not armies, adventurers. How many goblin villages have been destroyed since 3e started?
Why would that "pressure" disappear? So, I just don't buy that people affected by a demographic crises would be less likely to attack a threatening neighbour.
90% of them and their neighbors are gone. Most likely there is going to be a lot of empty land where they can disappear into.
Again, I don't see this following at all. Goblins and kobolds have light blindness; if 90% of the local goblin and kobold populations have just disappeared, along with various other underground dwellers, wouldn't these creatures fill underground areas that they could inhabit comfortably before going out onto marginal land on the surface?
That is true. I have never used them as underground dwellers and forgot about their adversion to sunlight. So that restricts them to dense forest and swamps after they destroy the dwarves and drow (if they were affected by the cataclysm).
And again, I don't think we know enough about the relative reproductive stats for the various species to assume that goblins and kobolds are the most efficient at reproducing if social controls are removed.
I am basing my arguement on the Dragon article I referenced earlier.
I think you are firmer footing saying this when you talk about species with which goblins and kobolds compete. But elves and humans are not really among those.
Huh? Goblins and kobolds are notorious raiders of human lands and when given the chance elven forests as well.
Also, look at the hit dice of various creatures when they reach adulthood. How many adult kobolds does it take to kill 10 adult bugbears? How many adult bugbears does it take to kill 10 adult kobolds?
Doesn't matter. Time is on the side of the kobolds and as long as they can wear down their compeditors over time, they win.
Or better still, how about another egg-laying greater HD species like Kuo-Toa?
They are fish and resticted to underground water. The only other people they are at war with are the aboleth. They do have the advantage of numbers, but slaves (skum) and magic tilt the favor to the aboleth. If the cataclysm affected both, I can see the kuo-toa getting the upper hand and within kuo-toa 4-5 generations (maybe less if they produce a lot of fry).
Furthermore, if kobolds became a really significant threat, wouldn't other creatures ally against them?
Yes and no. Humans, gnomes, halflings and elves would ally. But kobolds could, with magic and threats, gain goblins, ogres and other "humanoids" as allies. And in the numbers game, the latter win out because they all have a shorter generation.
It seems to me that your birthrate = everything argument is just way too deterministic.
In Earth's history the hunter-gather peoples have been pushed out by those with agriculture. Why? Because people who farm have more food and thus a higher population. More people means more soldiers.
But you haven't introduced the greatest variable in the whole conflict- magic. There are kobold sorcerers that are in the high teens in level, but their numbers are smaller than the elven wizards of comparable power. But then there maybe more low level spell casters among the kobolds than the elves (relating to the increased survival of spell casting beings over their relatives).
Also look at how an elf has to be 150 years old before he can be considered a first level anything. A kobold reachs that in 7. Kill an elf and it takes more than 150 years to replace him. Kill a kobold and it takes more than 7.
It would be nice if we could find out what caused this cataclysm and then it would be easier to determine the results.
