From VOM: Damien had the same projector rune carved into his left palm, matching the interface rune used for Jumping starships on his right palm. Unlike the other man, he also had Runes of Power carved into his forearms, shoulders, and upper back.
Just saying

Ha! Apparently I will need to fix that - most notably because while it is irrelevant whether Damien has a *projector* rune, he has always had an interface rune on each palm.

Also, is the extra power rune is on his chest or upper back? How the heck do you carve that?

All right, going back and checking the texts of the two books where Damien has all of his Runes instead of answering off the top of my head :P

Damien has EIGHT runes.
One projector rune and two interface runes on his palms.
Five Runes of Power - on his forearms, shoulders, and chest.

The second interface rune was missed and the fifth rune of power was mis-placed in the text of Voice of Mars. This will be corrected, though the correction probably will not propagate to anyone with the old Kindle version.
