Lands of The Hill
The Hill consists of four states: the Western Hill, the Central Hill, the Eastern Ridge, and the Eastern Forest.
The Western Hill
The Western Hill is a frontier land - there are dangerous bands of rats, settlements of squirrel traders (and squirrel brigands), and one or two human camps. The eastern part of the Western Hill has permanent and semi permanent settlements, mostly found between the Line (a geographic feature of the Western Hill) and the West-Central Ridge. There are fortunes to be made on the Western Hill for those brave and clever enough to survive the dangers.
Crooktail Fort
Crooktail Fort is the only permanent mouse settlement west of the Line on the Western Hill. There are a handful of semi-permanent villages beyond the Line, one or two of them growing enough that they'll soon be needing permanent walls and buildings.
The Fort is a trading post - mainly with squirrel traders, although there's some trade with rats and crows. There's new inventions like crossbows and fermented grain coming through the Fort, which is of much interest to the mice of the Grand Committee.
The Central Hill
The Central Hill is a far-flung, lush region of farmland and villages. It has the most settlements on the Hill, and most of the banking and political power. The Central Hill farms have historically been the source of most wealth on the Hill, although trade with squirrels in the Western Hill is starting to bring in new inventions and luxury items such as fermented grain, and there is worry among the powerful mice of the Central Hill.
The Eastern Ridge
To the east of the Central Hill is the Eastern Ridge. The villages of the Eastern Ridge are quiet and solemn. Most mice of the Eastern Ridge are members of the Great Hawk Church. Followers of the Church leave their dead on platforms to be taken to their celestial reward by the Great Hawk1. The Eastern Ridge folk are valued for their talents in carpentry and metalworking, and are often hired to build structures or to manufacture tools or weapons. Otherwise not much is known about the Eastern Ridge, as most outsiders have heard rumors that they're better off not being on the Eastern Ridge after dark.
Any hawks that are asked say that while they frequently snatch and eat mice, they prefer them live.
The Eastern Forest
The Eastern Forest is a chaotic land with several mice warlords, each with their warbands and followers. They spend most of their time trying to kill and steal from each other, but occasionally they'll go raiding on the Eastern Ridge or even into the easternmost settlements in the Central Hill. It is not known whether there are permanent settlements in the Eastern Forest.
