Uncanny X-Men (Uncanny X-Men Vol. 6 #3)

CATCH THE ELF! When new, lethally powerful and completely untrained young mutants show up on Rogue's doorstep with no knowledge of how they got there, a grieving Rogue seeks to take Xavier's place in guiding them to the light... while darkness from the past returns to destroy the X-Men, one at a time!
