Charles is Moirah's boyfriend and Rachael's older brother. He's a sweetheart, though clumsy and kind of doofy. He also works as an archaeologist, specialising in ancient indigenous tribal cultures, mostly those based in South America. During one such dig, he managed to dirupt a hidden tomb and opened something he wasn't supposed to.... which lead to him being possessed by the soul of a very ancient, very potent witchdoctor. Since then, he's had to cope with some new dark magic abilities, as seen here. The piercings aren't of his choice; they were placed there as charms to help contain the witchdoctor's soul; if you look carefully, you can see that one of his pupils' is slit.
