From "How Great Aspeigh Can Fit in Your Campaign":
Great Aspeigh easily fits into the Terra Ferax campaign, because it is a part of that campaign. If you want general guides to fit the hamlet elsewhere, this section is for you.
Because the hamlet is small, and many campaign maps ignore the smaller places, it can fit just about anywhere. Great Aspeigh is in plains and near a river. You may note that there is not a local temple only a local druid and he is almost worthless to higher level characters.
For low level characters, Great Aspeigh is a fine place to obtain goods and services. There are plenty of ruins and dangerous places to explore. If your adventurers need a base of operations, they can settle into an abandoned building.
A high level cleric could turn Great Aspeigh back into a thriving area again. It's a great place for old characters to retire to.
