or thanks on behalf of the team, I'm glad you like it. It's been six years since Warhammer 2.5 has been released, however, and none of us actively mod Civ3 anymore. It's safe to say that it's the final version.
I'm a great fan of both Civ and WFRP/WFB so I also play with every single one of those maps. 

I built thirst for power, but it's not letting me build the artifacts
Each artifact has its own technological prerequisite, so you have to research the tech before being able to build the corresponding artifact. You can see that in the tech tree.
