The “Age of Dominion” refers to the Declaration of Dominion (also called ‘Promise at Ahmfiphae’) in CY 191. Here it is proclaimed…
The dominion of the east shall initially be centered on the Far East, in the lands first encountered by the Blood of Saemon – Dundaria to the north and Osteni to the south and in between is the Valley of Sighs. This will preserve the Near East from settlement and desecration and contain the dwellers of Orrishai.
