Kevan Lannister is Murdered by Varys

In the epilogue, Ser Kevan Lannister, the Lord Regent, is shot with a crossbow by Varys, who has been hiding in the walls of the Red Keep. Varys also kills Grand Maester Pycelle. As Kevan lies dying, Varys explains that he killed him to prevent him from stabilizing Tommen's rule, which would have made it harder for the returning Aegon Targaryen to claim the throne. He leaves Kevan to die, surrounded by his 'little birds.'
