Here is the breakdown of the population of humanoids in the kingdom of Arnheim:
1,875 Hobgoblins (snow)
This is already a pretty good size for a tribe. I think I will have a very small offshoot, though, that lives separately.
45 Hobgoblins (1 4th-level leader)
1,830 Hobgoblins (1 12th-level leader and 3-4 8th-level lieutenants)
I’m using the steps outlined in Kent David Kelly’s excellent Game World Generator Deluxe Edition, which you can pick up here. With 434 pages of world building goodness, it is an absolute steal at $3.99 and even goes on sale below that.
