How many Elves?
At most there would be 30-300 Elves in a "lair" so 3d10x10=180.
And then, according to the Arneson FFC method, 10-60% of these are out and about at any time.
So at this particular time, 1d6=2, so 20% are out and about. That's 36 Elves.
According to the FCC there's 1 in 6 chance the wandering group is split, but I prefer 1 in 3.
1d6=6 so now we have two groups of 18.
1d6=2, so the first group is not split again. 1d6=1, and nor is the second group.
So we have a group of 18 Elves...
