This file will over-write the lighthouse background, so be sure to back up your scenario folder before you install.
To use this file, simply unzip to your scenario folder. This background shows a pyramid in the process of being built. Eventually, the Pharoah shows up to inspect his future tomb.
This file comes from a scenario I am the process of building--so this file can also be used as a template for your scenarios (just remember to give me credit in your readme file if you upload it). Look for my scenario, entitled "Rules of Succession," in about a month!
