" There is a small valley ten kilometers from the joint Mars colony, not visible from the surrounding desert, in the heart of the Melas Chasma in the Valles Marineris. As you approach it you will see three crosses -- one a traditional Latin cross, and two Celtic crosses. One of the Celtic crosses is next to the Latin cross. The other Celtic cross sits off to the side. It's obviously a small graveyard. And you're the first person to see this lonely place since I was there in 1985. You want to know what I know about it?
I know everything. I dug those graves. By hand. "
