Astonishing X-Men [2004] #25

It's the book you've been waiting for. The superstar team of Warren Ellis and Simone Bianchi are ready to take the X-Men to the "Second Stage"! "Messiah CompleX" pulled the X-Men team together, "Divided We Stand" tore them apart. Now the X-Men are back to business -- with a new look, a new base of operations, and a mystery to solve that will take them into previously uncharted territory and test them to their core!
