Cairo is the capital of Egypt and largest city in the Arab world and Africa. The city housed one of the strongest holds of the Blue Blood African community.

One of the many Paths of the Dead, which Catherine of Siena was tasked to seal with the Gate of Promise, was located in the city. The pyramid of Giza and the necropolis surrounding it had been built on top of the Path in ancient times to symbolise the place was linked to the kingdom of the Dead.
