In case there is any confusion, the Imperial Province of Orsinium decision can be taken under the following conditions, with the results below:

1) You hold Orsinium, or it is held by a vassal. This will simply drift Orsinium into the Empire.

2) Your culture has the Denizens of Lost Orsinium tradition. The kingdom which your capital is located in will become Orsinium, and it will be drifted into the Empire.

3) Any vassal has a culture with the Denizens of Lost Orsinium tradition, and is King tier or higher (will be chosen randomly if you have more then one). The kingdom which the vassal’s capital is located in will become Orsinium, and it will be drifted into the Empire.

Let me know if there are any questions 🙂
