Digging deep
While they were still students at university, they were having a lot of time to go out to locations with their professors around Germany and dig for things. Most of the time they would enjoy what they were doing, but they just could never stop talking about Egypt. The place consumed their minds.
Even on dig sites, where they were looking for something completely different and with no relationship to ancient Egypt, they would still talk about it. They knew that they had so much enthusiasm and excitement, they needed to take their talk to the next level. One day, an idea popped into their heads.
