While Emperor Trajan is constructing the biggest and most magnificent Emperor's forum in the history of Rome, each player is building up a Colonia in the province, far from the capital. A Colonia is a city in the format of a grid that is newly established by imperial decree. But as the Forum Trajanum is supposed to become the new outstanding landmark in Rome, Emperor and senate expect you to do nothing less than develop your Colonia into an important centre of your province, too.
