Ahh I'm a little later to the party, but I had no idea about the mummy/military thing
The more you know, I honestly thought the fame boost wouldn't apply to him since France is nowhere near Egypt, but what you all said totally makes sense.
It brings up a question though, would other Heroic Spirits know of him too? I know that in most shows, the Spirits know about each other's legends. With Ramases' being so well known and famous, it would be rather easy to determine who he is just based on attitude/mannerisms/attire.
I just want to figure his approach when the other servants meet him, and if there is going to be any point in him trying to hide who he is
