That's what I call a good start,

now comes the uneasy work.

I'll try to approach the number of regions we've got in HTW (68), let's say
65. It won't be simple, because the NE of the map is a huge area but short of
descriptions.
About factions:
I guess there are basic factions such as Cimmerians, Aquilonians, Khitai Empire and maybe Stygians
but can't say nothing about their power or wealth so, any information on which could be the most attractive regions will be considered.
