It's actually an ok show, think Winx, except it doesn't suck eggs. The show revolves around the 5 girls becoming 'Guardians of the Veil' and accuiring their powers after being given the Heart of Kandrakar (which belongs to the world that makes the center of existence). The first season they fight against Phobos who is an evil prince who took over his world of Meridian (only the princess is allowed to rule) while his little sister was still an infant.
As for their powers, Will at first has none, except for creating small attacks from the Heart, but eventually gains Quintessence (or Electricity). Irma controls water, and can make it out of thin air (from the beginning in show, but not until later in the comics). Taranee has power over fire, Cornelia can move earth and anything with earthen qualities (like algie from a pool) and Hay Lin controls air (even though some point her Chinese origins would not count air as an element).
All in all it's a good show, not too girly despite the fact it centers on female protaganists and still good with the action. If you're curious about the show, you can probably find some videos on Youtube.
