Geas

A spell or curse put appon someone to makesure they fulfil their task and dont betray their master. For instance a Geas could be put upon a servant to make sure that they stay loyal or upon a mercenary to make sure they dont double cross their employee.
Faliure to do so will result in the victim being killed in one way or another by the Geas.
Used alot by Celtic Shamans and Norse Guayla (witch doctors). Not used offensively as any magic user able to preform a Geas can easily destroy enemies in a multitude of other ways.

Code Geass: Lelouch of the Rebellion 

-often referred to as simply "Code Geass", is a Japanese anime series created by Sunrise with original character designs by Clamp.
-the series is set after Japan's conquest by the Holy Britannian Empire on August 10, 2010, a.t.b. with their powerful new robot weapons, the Knightmare Frames, stripping Japan and its citizens of all rights and freedoms and renaming the country Area 11. The titular Lelouch is an exiled Britannian prince, who has vowed to destroy his father, the Emperor, and Britannia. He gains the ability through the mysterious power of the Geass, becoming the leader of the resistance movement to fulfill his two wishes: to seek revenge for his mother and to construct a world in which his beloved sister Nunnally can live happily.
-all in all,I could not help but compare this show to Death Note and any Huge Mecha Show.there are many "rivalries" where two people square off against each other, either physically or mentally.Just as Light and L were great rivals, so do Lelouch and Suzaku fight a lot, but ultimately get more accomplished working together. there are many chess references throughout the show and some product placement. (Pizza Hut)

Jeff:"Want to watch a really epic anime?"
Craig:"I guess.But how do you mean 'epic'?"
Jeff:"Well picture Death Note with THREE other anime genres thrown into the mix plus like 30 more characters.Then you have Code Geass: Lelouch of the Rebellion."
Craig:"Sounds confusing."
Jeff:"It can be if you miss a single episode."

Gary:"OMG!Lelouch = epic win!Code Geass is amazing!"
Ash:"I disagree.While it is a good show with many things going for it,it also has some very unnecessary points."
Gary:"How do you mean?"
Ash:"Well they didn't need to keep Jeremiah alive, they made Lelouch's maid a NINJA(WTF?), the Emperor looks ridiculous with that wig, Nina (humps a table?what?), etc. etc.
Gary:"I don't get it."
Ash:"Just go to TV Tropes and look up the word NARM."

Code Geass 

Code Geass is the anime that all anime look up to. It has beautiful girls, mechas, explosions (Michael Bay approved), a plot that, if you attempt to spam watch the whole 2 seasons + bonus episodes and movies, will melt your brain with how awesome, slightly confusing, and how beautifully portrayed all the characters emotions and development come together. In short, Code Geass is awesomeness squared to the power of infinity.

Stranger 1: Hey, so, uh, by any chance do you watch Code Geass?
Stranger 2: NO. FUCKING. WAY. YOU WATCH THAT ANIME OF AWESOMENESS TOO!?
Both Stranger 1, and Stranger 2 start fanboying/girling all over the place.

Geass

Geass (ギアス, giasu?) is a mysterious ability which certain people can bestow upon others; C.C. is the most prominent character who grants the power of Geass. The form the Geass takes is different in each individual. C.C. calls Geass the Power of Kings (王の力, Ō no Chikara?), and is represented by a glowing, bird-like symbol.

Every Geass has its own unique set of restrictions, limitations, or idiosyncrasies. These factors allow a Geass to be defeated, or its power limited, by someone who is aware of its characteristics. All Geass abilities are related to the mind, influencing such aspects as will, thought, memory, emotion, and perception.

The power of Geass increases with use, usually starting in one eye. It can eventually spread to both eyes and become uncontrollable with repeated use. At this point, the one who granted the power can relinquish his or her immortality to the recipient, allowing the recipient to continue the cycle while the giver is allowed to die. The immortality is referred to as the giver's "Code," and grants the person immunity to Geass in exchange for their original power.

"Geass" may be an intentional corruption of the word "geas" or "geis", a term for a type of magical contract in Irish mythology.

Lelouch- I, Lelouch vi Britannia, command you to die!

Enemy- Yes, my Lord! -bang-

Lelouch- -chuckles- The Geass.. never fails...
