Prologue: Merry Christmas to you all!

The Grail War continues, as Rogue, Berserker, Peter and Artoria are sent to Canada with the clawed Wolverine where rumors of a Servant have been whispered among the Mages of the Clocktower.

As Spider-Man finds himself more desperate to protect Saber, he soon starts to turn to a darker power lurking in him.. a power that might force Saber to ask herself the most daunting question of all.
