Ok I've never read DC comics much but recently I've developed a bit of an interest in the Green Lantern. I know a little bit of the history about the character. And I've been tossing around the idea of my players taking part in the Green Lantern Corps unfortunately I don't know alot about the powers of the rings potental other than I can have them design almost any power for thier rings. I did a search on the boards here and found some useful info on the corps and how the rings could be designed..e.g. recharging, weakness to the color yellow,etc....
