Founder of Grimsborough

Statue of William Cooper.

The city of Grimsborough was founded by William Cooper in 1845. Per his descendant, Ashton Cooper, Grimsborough was only the leftovers of a small Pilgrim settlement before William built it.

It is known that William, at some point in his life, settled in the city's Historical Center along with his pet dog, Ellington.

William also has a statue of him built in Cooper Park in the Financial Center.


Grimsborough features the first fifty-six cases of the game, located across the six different districts of the city:
