Indeed at this time [the War of the Ring] they were more disposed to side with Saruman, and many of their warriors had joined Saruman's forces....

Not completely disposed. Not all of their warriors. As I'm sure you can see, not all of the people and warriors of this region were evil. Some still were loyal to Théoden King, and these should be represented in the biome. So Rohirric NPCs should spawn, though rarer than their counterparts, and a few structures of Rohan. It seems the simplest way to represent this divided people.
