The Krakoa Era of the X-Men has brought the team new challenges, including governing their own country. To do this, they created the Quiet Council, a governing body consisting of twelve mutants. The Quiet Council has been leading Krakoa through its short yet tumultuous existence. Things went well at first, but events like Sins Of Sinister and books like Immortal X-Men have been outlining the problems the Council faces, within and without.
