The Merge leaves the memories and abilities of two American soldiers from Fort Benning in the bodies of Don Hernando Francisco de Montoya y Cortez, a conquistador of the Nasine Empire, and Vectoria, a half-orc intercessor of Twir, the goddess of scribes. In a world filled with slavery and human sacrifice, they are determined to let freedom ring.
Not everyone is in agreement with their plans. The Count they work for throws them out. The Nasine Royal Governor isn't impressed. When the Church of Noron-for their own reasons-forces him to give Francisco a title, he then does everything in his power to make him fail. Preferably fail fatally.
And while Twir and Noron are in favor of the project the other gods are too busy squabbling over access to the Merge world to care about a couple of adventurers and a small group of orcs. Meanwhile the governments in Nasine and the rest of Centriaum have noticed that something strange is going on in the Orclands and are coming to investigate.
As for the orcs themselves, all they want to do is feed Francisco, Vectoria and the gang to their gods.
